Struct TreeModelRef 

Source 
pub struct TreeModelRef<'a, Id, C> { /* private fields */ }
Expand description

A zero-copy adapter over roots and a child accessor for arbitrary storage.

Implementations§

Source§

impl<'a, Id, C> TreeModelRef<'a, Id, C>

Source

pub const fn new(roots: &'a [Id], children: C, revision: TreeRevision) -> Self

Creates an adapter. Tree validity remains an invariant of the source storage.

Source

pub const fn with_size_hint(self, size_hint: usize) -> Self

Sets an approximate node count for cache reservation.

Trait Implementations§

Source§

impl<'a, Id, C> TreeModel for TreeModelRef<'a, Id, C>
where Id: Copy + Eq + Hash, C: Fn(Id) -> TreeChildren<'a, Id>,

Source§

type Id = Id

The node identifier type.
Source§

fn roots(&self) -> impl Iterator<Item = Self::Id> + '_

Returns forest roots in deterministic order.
Source§

fn children(&self, id: Self::Id) -> TreeChildren<'_, Self::Id>

Returns the node’s child state and loaded children.
Source§

fn revision(&self) -> TreeRevision

Returns the revision of the model structure and display data.
Source§

fn size_hint(&self) -> usize

Returns an approximate number of available nodes.
