Struct dyn_dyn::AnyDynMetadata

source · [−]

pub struct AnyDynMetadata(_);

Expand description

An untyped metadata that corresponds to the metadata that would be used for a trait object.

Implementations

source

impl AnyDynMetadata

source

pub const unsafe fn downcast<T: DynDynCastTarget + ?Sized>(
self
) -> DynMetadata<T>

Downcasts this untyped metadata into typed metadata for a trait object referring to a particular trait.

Safety

This untyped metadata must have originally been constructed by converting a DynMetadata<T>.
