[−][src]Enum log::Level
An enum representing the available verbosity levels of the logger.
Typical usage includes: checking if a certain Level
is enabled with
log_enabled!
, specifying the Level
of
log!
, and comparing a Level
directly to a
LevelFilter
.
Variants
Error
The "error" level.
Designates very serious errors.
Warn
The "warn" level.
Designates hazardous situations.
Info
The "info" level.
Designates useful information.
Debug
The "debug" level.
Designates lower priority information.
Trace
The "trace" level.
Designates very low priority, often extremely verbose, information.
Methods

[src]
pub fn max() -> Level
[src]

pub fn to_level_filter(&self) -> LevelFilter
