Operation on runtime child storages.
Stuff to do with the runtime’s storage.
A contiguous growable array type with heap-allocated contents, written
Vec<T>.Autogenerated weights for virto_payment
Macros
Panic if an expression doesn’t evaluate to
Ok.Evaluate
$x:expr and if not true return Err($y:expr).Return Err of the expression:
return Err($expression);.Structs
An error type that indicates that the origin is invalid.
Hash storage keys with blake2 128
Hash storage keys with
concat(blake2_128(key), key)Hash storage keys with blake2 256
Blake2-256 Hash implementation.
A bounded map based on a B-Tree.
A bounded vector.
A pointer type that uniquely owns a heap allocation of type
T.Const getter for a basic type.
A wrapper around a
StorageMap and a StorageValue<Value=u32> to keep track of how many items
are in a map, without needing to iterate all the values.A fixed point number representation in the range.
Fixed Point 128 bits unsigned, range = [0.000000000000000000, 340282366920938463463.374607431768211455]
Implement Get by returning Default for any type that implements Default.
Store the key directly.
A lookup implementation returning the input value.
Inherent data to include in a block.
A type used exclusively by storage maps as their key type.
Implement QueryKindTrait with query being
Option<Value>A pallet identifier. These are per pallet and should be stored in a registry somewhere.
The PaymentDetail struct stores information about the payment/escrow
A “payment” in virto network is similar to an escrow, it is used to
guarantee proof of funds and can be released once an agreed upon condition
has reached between the payment creator and recipient. The payment lifecycle
is tracked using the state field.
A fixed point representation of a number in the range [0, 1].
Zero-sized type used to mark things that “act like” they own a
T.Implement QueryKindTrait with query being
Result<Value, PalletError>The details of a scheduled task
A type that allow to store values for
(key1, key2) couple. Similar to StorageMap but allow
to iterate and remove value associated to first key.A type that allow to store value for given key. Allowing to insert/remove/iterate on values.
A type that allow to store values for an arbitrary number of keys in the form of
(Key<Hasher1, key1>, Key<Hasher2, key2>, ..., Key<HasherN, keyN>).A type that allow to store a value.
The storage version of a pallet.
Hash storage keys with
concat(twox64(key), key)Hash storage keys with twox 128
Hash storage keys with twox 256
Information concerning a valid transaction.
Implement QueryKindTrait with query being
ValueA contiguous growable array type, written as
Vec<T>, short for ‘vector’.Reasons for moving funds out of an account.
Enums
Status of funds.
A generalized group of dispatch types.
Reason why a dispatch call failed.
Simple boolean for whether an account needs to be kept in existence.
An invalid transaction validity.
The
PaymentState enum tracks the possible states that a payment can be in.
When a payment is ‘completed’ or ‘cancelled’ it is removed from storage and
hence not tracked by a state.Explicit enum to denote if a transaction pays fee or not.
Origin for the System pallet.
Types of Tasks that can be scheduled in the pallet
The source of the transaction.
Errors that can occur while checking the validity of a transaction.
An unknown transaction validity.
Constants
The number of bytes of the module-specific
error field defined in [ModuleError].
In FRAME, this is the maximum encoded size of a pallet error type.Traits
This type can be converted into and possibly from an AccountId (which itself is generic).
Performs addition that returns
None instead of wrapping around on
overflow.A trait for querying whether a type can be said to “contain” a value.
Abstraction over a fungible assets system.
Trait that allows zero-copy read of value-references from slices in LE format.
DisputeResolver trait defines how to create/assign judges for solving
payment disputes
Trait that allows zero-copy write of value-references to slices in LE format.
A marker trait that tells the compiler that a type encode to the same representation as another
type.
Some sort of check on the origin is performed by this object.
Fee Handler trait that defines how to handle marketplace fees to every
payment/swap
A trait to define the build function of a genesis config, T and I are placeholder for pallet
trait and pallet instance.
A trait for querying a single value from a type.
A
Dispatchable function (aka transaction) that can carry some static information along with
it, using the #[weight] attribute.Provides information about the storage version of a pallet.
Abstraction around hashing
The pallet hooks trait. Implementing this lets you express some logic to execute.
Trait to be used when types are exactly same.
A currency whose accounts can have liquidity restrictions.
Items implementing
MaxEncodedLen have a statically known maximum encoded size.A type that implements Serialize, DeserializeOwned and Debug when in std environment.
A type that can be used in runtime structures.
Defines a multiplicative identity element for
Self.Provides information about the pallet itself and its setup in the runtime.
A type that can be used as a parameter in a dispatchable function.
trait that defines how to create/release payments for users
Something that implements a fixed point ration with an arbitrary granularity
X, as parts per
X.A pallet that provides or verifies an inherent extrinsic will implement this trait.
A currency where funds can be reserved from the user.
Saturating arithmetic operations, returning maximum or minimum values instead of overflowing.
Means of changing one type into another in a manner dependent on the source type.
This variant is different to
Lookup in that it doesn’t (can cannot) require any
context.A trait to give information about storage.
Implementors return their meta type information.
A trait for querying a single value from a type defined in the trait.
Type that can be dispatched with an origin but without checking the origin filter.
Something that can validate unsigned extrinsics for the transaction pool.
Defines an additive identity element for
Self.Functions
Ensure that the origin
o represents an unsigned extrinsic. Returns Ok or an Err otherwise.Ensure that the origin
o represents the root. Returns Ok or an Err otherwise.Ensure that the origin
o represents a signed extrinsic (i.e. transaction).
Returns Ok with the account that signed the extrinsic or an Err otherwise.Ensure that the origin
o represents either a signed extrinsic (i.e. transaction) or the root.
Returns Ok with the account that signed the extrinsic, None if it was root, or an Err
otherwise.Type Definitions
Type alias for the
BlockNumber associated type of system config.Unaugmented version of
DispatchResultWithPostInfo that can be returned from
dispatchable functions and is automatically converted to the augmented type. Should be
used whenever the PostDispatchInfo does not need to be overwritten. As this should
be the common case it is the implicit return type when none is specified.The return type of a
Dispatchable in frame. When returned explicitly from
a dispatchable function it allows overriding the default PostDispatchInfo
returned from a dispatch.An identifier for an inherent.
Type alias for the
Origin associated type of system config.list of ScheduledTasks, stored as a BoundedBTreeMap
Minimum number of blocks a transaction will remain valid for.
TransactionLongevity::max_value() means “forever”.Priority for a transaction. Additive. Higher is better.
Tag for a transaction. No two transactions with the same tag should be placed on-chain.
Information on a transaction’s validity and, if valid, on how it relates to other transactions.

Debug, if std is enabled it uses frame_support::DebugNoBound, if std is not
enabled it just returns "<stripped>".
This behaviour is useful to prevent bloating the runtime WASM blob from unneeded code.
