Struct 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.

Trait Implementations

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
