Enum log::LogLevel

pub enum LogLevel {
    Error,
    Warn,
    Info,
    Debug,
    Trace,
}

[−] Expand description

An enum representing the available verbosity levels of the logging framework

A LogLevel may be compared directly to a LogLevelFilter.

Variants

Error

[−] Expand description

The "error" level.

Designates very serious errors.

Warn

[−] Expand description

The "warn" level.

Designates hazardous situations.

Info

[−] Expand description

The "info" level.

Designates useful information.

Debug

[−] Expand description

The "debug" level.

Designates lower priority information.

Trace

[−] Expand description

The "trace" level.

Designates very low priority, often extremely verbose, information.

Methods

impl LogLevel

fn max() -> LogLevel[−]

Returns the most verbose logging level.

fn to_log_level_filter(&self) -> LogLevelFilter[−]

Converts the LogLevel to the equivalent LogLevelFilter.

Trait Implementations

impl Debug for LogLevel

fn fmt(&self, __arg_0: &mut Formatter) -> Result[−]

Formats the value using the given formatter.

impl Eq for LogLevel

impl Copy for LogLevel

impl Clone for LogLevel

fn clone(&self) -> LogLevel[−]

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)[−]

Performs copy-assignment from source.

impl PartialEq for LogLevel

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 PartialEq<LogLevelFilter> for LogLevel

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 PartialOrd for LogLevel

fn partial_cmp(&self, other: &LogLevel) -> 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.

impl PartialOrd<LogLevelFilter> for LogLevel

impl Ord for LogLevel

fn cmp(&self, other: &LogLevel) -> Ordering[−]

This method returns an Ordering between self and other.

impl FromStr for LogLevel

type Err = ()

The associated error which can be returned from parsing.

fn from_str(level: &str) -> Result<LogLevel, ()>[−]

Parses a string s to return a value of this type.

impl Display for LogLevel

fn fmt(&self, fmt: &mut Formatter) -> Result[−]

Formats the value using the given formatter.
