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

source

impl LevelFilter

source

pub fn max() -> LevelFilter

Returns the most verbose logging level filter.

source

pub fn to_level(&self) -> Option<Level>

Converts self to the equivalent Level.

Returns None if self is LevelFilter::Off.

source

pub fn as_str(&self) -> &'static str

Returns the string representation of the LevelFilter.

This returns the same string as the fmt::Display implementation.
