[][src]Struct tracing::level_filters::LevelFilter

pub struct LevelFilter(_);

A filter comparable to trace verbosity Level.

If a Level is considered less than a LevelFilter, it should be considered disabled; if greater than or equal to the LevelFilter, that level is enabled.

Note that this is essentially identical to the Level type, but with the addition of an OFF level that completely disables all trace instrumentation.

Implementations

impl LevelFilter[src]

pub const OFF: LevelFilter[src]

The "off" level.

Designates that trace instrumentation should be completely disabled.

pub const ERROR: LevelFilter[src]

The "error" level.

Designates very serious errors.

pub const WARN: LevelFilter[src]

The "warn" level.

Designates hazardous situations.

pub const INFO: LevelFilter[src]

The "info" level.

Designates useful information.

pub const DEBUG: LevelFilter[src]

The "debug" level.

Designates lower priority information.

pub const TRACE: LevelFilter[src]

The "trace" level.

Designates very low priority, often extremely verbose, information.

pub const fn from_level(level: Level) -> Self[src]

Returns a LevelFilter that enables spans and events with verbosity up to and including level.

pub const fn into_level(self) -> Option<Level>[src]

Returns the most verbose Level that this filter accepts, or None if it is OFF.
