[−][src]Struct tracing::level_filters::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.
Methods
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.
