Struct microkelvin::Branch

pub struct Branch<'a, C, A>(_);

Represents an immutable branch view into a collection.

Branches are always guaranteed to point at a leaf, and can be de-referenced to the pointed-at leaf.

Implementations

impl<'a, C, A> Branch<'a, C, A>

pub fn depth(&self) -> usize

Returns the depth of the branch

pub fn levels(&self) -> &[Level<'_, C, A>]

Returns a slice into the levels of the tree.

impl<'a, C, A> Branch<'a, C, A>where
    C: Compound<A>,

pub fn map_leaf<M>(
    self,
    closure: for<'b> fn(_: &'b C::Leaf) -> &'b M
) -> MappedBranch<'a, C, A, M>

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

pub fn walk<W>(root: &'a C, walker: W) -> Option<Self>where
    W: Walker<C, A>,

Performs a tree walk, returning either a valid branch or None if the walk failed.

Trait Implementations

impl<'a, C: Debug, A: Debug> Debug for Branch<'a, C, A>

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

Formats the value using the given formatter.

impl<'a, C, A> Deref for Branch<'a, C, A>where
    C: Compound<A>,

type Target = <C as Compound<A>>::Leaf

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a, C, A> IntoIterator for Branch<'a, C, A>where
    C: Compound<A>,

type Item = &'a <C as Compound<A>>::Leaf

The type of the elements being iterated over.

type IntoIter = BranchIterator<'a, C, A, AllLeaves>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
