Struct ObsCallsite 

pub struct ObsCallsite { /* private fields */ }

Static metadata for a single emit site. Constructed by codegen via the const fn constructor — no heap allocation, no first-emit cost.

See spec 11 § 2.

Implementations

impl ObsCallsite

pub const fn new( full_name: &'static str, default_sev: Severity, module: &'static str, file: &'static str, line: u32, ) -> ObsCallsite

Construct a callsite. Intended for use by codegen at static init; the const-fn shape means no heap allocation on first emit.

pub fn enabled(&self, current_gen: u32) -> EnabledOutcome

Hot-path enabled check.

Returns true if this callsite might fire (Sometimes / Always); the caller is then expected to invoke Observer::enabled only when the result is Sometimes.

current_gen is the observer’s generation(). On a generation mismatch the cache is reset to Unknown and the caller re-probes.

pub fn cache(&self, interest: Interest, current_gen: u32)

Update the cached interest after probing the observer.

pub fn reset_cache(&self)

Force the cache to Unknown so the next emit re-probes. Used by tests; production reload uses ObsCallsite::cache with the new generation, which has the same effect.

pub const fn full_name(&self) -> &'static str

Fully qualified event name.

pub const fn default_sev(&self) -> Severity

Default severity declared by the schema.

pub const fn module(&self) -> &'static str

module_path!() from the emit site.

pub const fn file(&self) -> &'static str

file!() from the emit site.

pub const fn line(&self) -> u32

line!() from the emit site.

impl Debug for ObsCallsite

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
