Enum log::LevelFilter
source · [−]#[repr(usize)]
pub enum LevelFilter {
Off,
Error,
Warn,
Info,
Debug,
Trace,
}
Expand description
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.
Implementations
sourceimpl LevelFilter
impl LevelFilter
sourcepub fn max() -> LevelFilter
pub fn max() -> LevelFilter
Returns the most verbose logging level filter.
sourcepub fn to_level(&self) -> Option<Level>
pub fn to_level(&self) -> Option<Level>
Converts self
to the equivalent Level
.
Returns None
if self
is LevelFilter::Off
.
sourcepub fn as_str(&self) -> &'static str
pub fn as_str(&self) -> &'static str
Returns the string representation of the LevelFilter
.
This returns the same string as the fmt::Display
implementation.
sourcepub fn iter() -> impl Iterator<Item = Self>
pub fn iter() -> impl Iterator<Item = Self>
Iterate through all supported filtering levels.
The order of iteration is from less to more verbose filtering.
Examples
use log::LevelFilter;
let mut levels = LevelFilter::iter();
assert_eq!(Some(LevelFilter::Off), levels.next());
assert_eq!(Some(LevelFilter::Trace), levels.last());
