Trait MetadataWeave 

pub trait MetadataWeave<K, N, T, M>: Weave<K, N, T>
where
    K: Hash + Copy + Eq + Ord,
    N: Node<K, T>,
{
    // Required methods
    fn metadata(&self) -> &M;
    fn metadata_mut<O>(&mut self, callback: impl FnOnce(&mut M) -> O) -> O;
}

A Weave containing document-wide metadata.

Panics

All panics should be assumed to leave the Weave in a malformed state unless otherwise specified by the implementation.

Required Methods

fn metadata(&self) -> &M

Returns a reference to the Weave’s associated metadata.

fn metadata_mut<O>(&mut self, callback: impl FnOnce(&mut M) -> O) -> O

Mutable access to the Weave’s associated metadata.

Panics

May panic if callback panics.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
