Trait TracingConfig 

pub trait TracingConfig {
    // Required methods
    fn quiet(&self) -> u8;
    fn verbose(&self) -> u8;

    // Provided methods
    fn with_ansi(&self) -> bool { ... }
    fn with_current_span(&self) -> bool { ... }
    fn with_file(&self) -> bool { ... }
    fn with_line_number(&self) -> bool { ... }
    fn with_level(&self) -> bool { ... }
    fn with_span_events(&self) -> Option<FmtSpan> { ... }
    fn with_span_list(&self) -> bool { ... }
    fn with_target(&self) -> bool { ... }
    fn with_thread_ids(&self) -> bool { ... }
    fn with_thread_names(&self) -> bool { ... }
}

Implement this trait to supply tracing configuration that can be used to build a Layer with functions such as full_filtered.

Required Methods

fn quiet(&self) -> u8

Get the quiet count (these are normally pulled from the command line arguments)

fn verbose(&self) -> u8

Get the verbose count (these are normally pulled from the command line arguments)

Provided Methods

fn with_ansi(&self) -> bool

Sets whether or not the formatter emits ANSI terminal escape codes for colors and other text formatting. This defaults to true

fn with_current_span(&self) -> bool

Available on crate feature json only.

Sets whether or not the formatter will include the current span in formatted events. This defaults to false

fn with_file(&self) -> bool

Sets whether or not an event’s source code file path is displayed. This defaults to false

fn with_line_number(&self) -> bool

Sets whether or not an event’s source code line number is displayed. This defaults to false

fn with_level(&self) -> bool

Sets whether or not an event’s level is displayed. This defaults to true

fn with_span_events(&self) -> Option<FmtSpan>

Configures how synthesized events are emitted at points in the span lifecycle. This defaults to None. See with_span_event

fn with_span_list(&self) -> bool

Available on crate feature json only.

Sets whether or not the formatter will include a list (from root to leaf) of all currently entered spans in formatted events. This defaults to false

fn with_target(&self) -> bool

Sets whether or not an event’s target is displayed. This defaults to false

fn with_thread_ids(&self) -> bool

Sets whether or not the thread ID of the current thread is displayed when formatting events. This defaults to false

fn with_thread_names(&self) -> bool

Sets whether or not the name of the current thread is displayed when formatting events. This defaults to false

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
