Enum pallet_tenancy::child::ChildType

pub enum ChildType {
    ParentKeyId,
}

Type of child. It does not strictly define different child type, it can also be related to technical consideration or api variant.

Variants

ParentKeyId

If runtime module ensures that the child key is a unique id that will only be used once, its parent key is used as a child trie unique id.

Implementations

impl ChildType

pub fn new(repr: u32) -> Option<ChildType>

Try to get a child type from its u32 representation.

pub fn from_prefixed_key<'a>(
    storage_key: &'a PrefixedStorageKey
) -> Option<(ChildType, &'a [u8])>

Transform a prefixed key into a tuple of the child type and the unprefixed representation of the key.

pub fn parent_prefix(&self) -> &'static [u8]

Returns the location reserved for this child trie in their parent trie if there is one.

Trait Implementations

impl Clone for ChildType

fn clone(&self) -> ChildType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ChildType

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq<ChildType> for ChildType

fn eq(&self, other: &ChildType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
