pub struct LoggerService { /* private fields */ }

Built-in logging service bound to a context.

Implementations

impl LoggerService

pub fn logger(&self, name: Option<String>) -> Logger

Create a logger. An intercept name overrides the fiber-derived name; an explicit name overrides both.

pub fn exporter<E: Exporter>(&self, exporter: E) -> Result<EffectHandle>

Register an exporter owned by the current fiber.

pub fn exporter_fn<F>( &self, config: ExporterConfig, callback: F, ) -> Result<EffectHandle>

where F: Fn(&Message) + Send + Sync + 'static,

Register an exporter callback with explicit config.

pub fn exporter_arc(&self, exporter: Arc<dyn Exporter>) -> Result<EffectHandle>

Register an already shared exporter.

pub fn buffer(&self) -> Vec<Message>

Snapshot the chronological bounded message buffer.

pub fn set_buffer_size(&self, size: usize)

Set buffer capacity, immediately trimming oldest records.

pub fn buffer_size(&self) -> usize

Current buffer capacity.

pub fn exporter_count(&self) -> usize

Number of registered exporters.

pub fn clear_buffer(&self)

Remove buffered messages without touching exporters.
