#[repr(usize)]pub enum Level {
Error = 1,
Warn = 2,
Info = 3,
Debug = 4,
Trace = 5,
}
Expand description
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 = 1
The “error” level.
Designates very serious errors.
Warn = 2
The “warn” level.
Designates hazardous situations.
Info = 3
The “info” level.
Designates useful information.
Debug = 4
The “debug” level.
Designates lower priority information.
Trace = 5
The “trace” level.
Designates very low priority, often extremely verbose, information.
Implementations§
source§impl Level
impl Level
sourcepub fn to_level_filter(&self) -> LevelFilter
pub fn to_level_filter(&self) -> LevelFilter
Converts the Level
to the equivalent LevelFilter
.
sourcepub fn as_str(&self) -> &'static str
pub fn as_str(&self) -> &'static str
Returns the string representation of the Level
.
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 logging levels.
The order of iteration is from more severe to less severe log messages.
Examples
use log::Level;
let mut levels = Level::iter();
assert_eq!(Some(Level::Error), levels.next());
assert_eq!(Some(Level::Trace), levels.last());
