Struct microkelvin::Branch
source · [−]pub struct Branch<'a, C, A, I>(_)
where
C: Archive;Expand description
Reprents an immutable branch view into a collection.
Branche are always guaranteed to point at a leaf, and can be dereferenced to the pointed-at leaf.

sourcepub fn map_leaf<M>(
self,
closure: fn(_: MaybeArchived<'a, C::Leaf>) -> M
) -> MappedBranch<'a, C, A, I, M> where

self,
closure: fn(_: MaybeArchived<'a, C::Leaf>) -> M
) -> MappedBranch<'a, C, A, I, M> where
C: Compound<A, I>,
M: 'a,
Returns a branch that maps the leaf to a specific value. Used in maps for example, to get easy access to the value of the KV-pair
sourcepub fn leaf(&self) -> MaybeArchived<'_, C::Leaf>
pub fn leaf(&self) -> MaybeArchived<'_, C::Leaf>
Returns a reference to the currently pointed-at leaf

C::Archived: ArchivedCompound<C, A, I> + for<'any> CheckBytes<DefaultValidator<'any>>,
C::Leaf: 'a + Archive,
A: Annotation<C::Leaf>,
W: Walker<C, A, I>,
Performs a tree walk, returning either a valid branch or None if the walk failed.

C::Archived: ArchivedCompound<C, A, I> + for<'any> CheckBytes<DefaultValidator<'any>>,
C::Leaf: 'a + Archive,
A: Annotation<C::Leaf>,
W: Walker<C, A, I>,
Performs a tree walk, returning either a valid branch or None if the walk failed.
