Struct tracing_core::callsite::DefaultCallsite

pub struct DefaultCallsite { /* private fields */ }

A default Callsite implementation.

Implementations

impl DefaultCallsite

pub const fn new(meta: &'static Metadata<'static>) -> Self

Returns a new DefaultCallsite with the specified Metadata.

pub fn register(&'static self) -> Interest

Registers this callsite with the global callsite registry.

If the callsite is already registered, this does nothing. When using DefaultCallsite, this method should be preferred over [tracing_core::callsite::register], as it ensures that the callsite is only registered a single time.

Other callsite implementations will generally ensure that callsites are not re-registered through another mechanism.

See the documentation on callsite registration for details on the global callsite registry.

pub fn interest(&'static self) -> Interest

Returns the callsite’s cached Interest, or registers it for the first time if it has not yet been registered.
