pub trait Callsite: Sync {
    fn set_interest(&self, interest: Interest);
    fn metadata(&self) -> &Metadata<'_>;
}
Expand description

Trait implemented by callsites.

These functions are only intended to be called by the callsite registry, which correctly handles determining the common interest between all collectors.

See the module-level documentation for details on callsites.

Required Methods

Sets the Interest for this callsite.

See the documentation on callsite interest caching for details.

Returns the metadata associated with the callsite.

Note: Implementations of this method should not produce Metadata that share the same callsite Identifier but otherwise differ in any way (e.g., have different names).
