Struct AutoSpan 

pub struct AutoSpan { /* private fields */ }

Auto-ending span that logs duration on drop.

Unlike Span, this type automatically logs its duration when it goes out of scope, making it ideal for RAII-style usage.

Implementations

impl AutoSpan

pub fn new(ctx: &RequestContext, name: impl Into<String>) -> Self

Creates a new auto-ending span using the default LogConfig.

The span end event is emitted at DEBUG level, so it will only be visible if DEBUG logging is enabled.

pub fn new_with_config( ctx: &RequestContext, config: LogConfig, name: impl Into<String>, ) -> Self

Creates a new auto-ending span using an explicit LogConfig.

The span end event is emitted at DEBUG level, so it will only be visible if DEBUG logging is enabled.

Trait Implementations

impl Drop for AutoSpan

fn drop(&mut self)

Executes the destructor for this type.
