Enum log::LogLevel

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

An enum representing the available verbosity levels of the logging framework

A LogLevel may be compared directly to a LogLevelFilter.

Variants

Error

The "error" level.

Designates very serious errors.

Warn

The "warn" level.

Designates hazardous situations.

Info

The "info" level.

Designates useful information.

Debug

The "debug" level.

Designates lower priority information.

Trace

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

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

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 Ord for LogLevel

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

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.
