Metadata read-only access trait.

Required Methods

fn id(&'a self) -> &'a Uuid

Get the ID from metadata.

fn name(&'a self) -> Option<&'a N>

Get the name from metadata.

fn kind(&'a self) -> Option<&'a K>

Get the kind from metadata.

fn labels(&'a self) -> impl Iterator<Item = &'a L>

where L: 'a,

Get the labels from metadata.

fn weights(&'a self) -> impl Iterator<Item = (&'a W, &'a WV)>

where W: 'a, WV: 'a,

Get the weights from metadata.

fn annotations(&'a self) -> impl Iterator<Item = (&'a A, &'a AV)>

where A: 'a, AV: 'a,

Get the annotations from metadata.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
