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.

Trait Implementations

impl Clone for LogLevelFilter

fn clone(&self) -> LogLevelFilter

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PartialEq for LogLevelFilter

fn eq(&self, other: &LogLevelFilter) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialEq<LogLevel> for LogLevelFilter

fn eq(&self, other: &LogLevel) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd for LogLevelFilter

fn partial_cmp(&self, other: &LogLevelFilter) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
