Enum LogLevel

pub enum LogLevel {
    ALL,
    NONE,
    DISABLED,
    DEBUG,
    TRACE,
    VERBOSE,
    INFO,
    WARN,
    ERROR,
    FATAL,
    CRITICAL,
}

An enumeration of the different levels that a log message can have, ordered by severity.

Variants

ALL

ALL: The log level includes all levels.

NONE

NONE: No logging.

DISABLED

DISABLED: Logging is disabled.

DEBUG

DEBUG: Debugging information, typically useful for developers.

TRACE

TRACE: Finer-grained informational events than DEBUG.

VERBOSE

VERBOSE: Detailed logging, often more detailed than INFO.

INFO

INFO: Informational messages that highlight the progress of the application.

WARN

WARN: Potentially harmful situations.

ERROR

ERROR: Error events that might still allow the application to continue running.

FATAL

FATAL: Very severe error events that will presumably lead the application to abort.

CRITICAL

CRITICAL: Critical conditions, often requiring immediate attention.

Implementations

impl LogLevel

pub fn includes(self, other: LogLevel) -> bool

Checks if the current log level includes another log level.

Arguments

• other - The log level to compare with.

Examples

use rlg::log_level::LogLevel;
assert!(LogLevel::ERROR.includes(LogLevel::DEBUG)); // ERROR includes DEBUG
assert!(!LogLevel::DEBUG.includes(LogLevel::WARN)); // DEBUG does not include WARN
assert!(LogLevel::WARN.includes(LogLevel::DEBUG)); // WARN includes DEBUG

pub fn to_numeric(self) -> u8

Converts the log level to its corresponding numeric value, similar to syslog severity levels.

Examples

use rlg::log_level::LogLevel;
assert_eq!(LogLevel::ERROR.to_numeric(), 8);
assert_eq!(LogLevel::DEBUG.to_numeric(), 3);

pub fn from_numeric(value: u8) -> Option<Self>

Creates a LogLevel from a numeric value, similar to syslog severity levels.

Arguments

• value - The numeric value to convert.

Examples

use rlg::log_level::LogLevel;
assert_eq!(LogLevel::from_numeric(8), Some(LogLevel::ERROR));
assert_eq!(LogLevel::from_numeric(5), Some(LogLevel::VERBOSE));

Performs copy-assignment from source.

impl Debug for LogLevel

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LogLevel

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LogLevel

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for LogLevel

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for LogLevel

type Err = ParseLogLevelError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

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

impl Hash for LogLevel

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for LogLevel

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

impl PartialEq for LogLevel

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

Tests for self and other values to be equal, and is used by ==.

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

type Error = ParseLogLevelError

The type returned in the event of a conversion error.

fn try_from(value: String) -> Result<Self, Self::Error>

Performs the conversion.
