[−][src]Enum structopt_flags::LevelFilter
An enum representing the available verbosity level filters of the logger.
A LevelFilter
may be compared directly to a Level
. Use this type
to get and set the maximum log level with max_level()
and set_max_level
.
Variants
Off
A level lower than all log levels.
Error
Corresponds to the Error
log level.
Warn
Corresponds to the Warn
log level.
Info
Corresponds to the Info
log level.
Debug
Corresponds to the Debug
log level.
Trace
Corresponds to the Trace
log level.
Methods
impl LevelFilter
[src]
pub fn max() -> LevelFilter
[src]
Returns the most verbose logging level filter.
pub fn to_level(&self) -> Option<Level>
[src]
Converts self
to the equivalent Level
.
Returns None
if self
is LevelFilter::Off
.
