Enum log::LogLevelFilter

pub enum LogLevelFilter {
    Off,
    Error,
    Warn,
    Info,
    Debug,
    Trace,
}

An enum representing the available verbosity level filters of the logging framework.

A LogLevelFilter may be compared directly to a LogLevel.

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 LogLevelFilter

fn max() -> LogLevelFilter

Returns the most verbose logging level filter.

fn to_log_level(&self) -> Option<LogLevel>

Converts self to the equivalent LogLevel.

Returns None if self is LogLevelFilter::Off.
