Enum LogLevel 

#[repr(u8)]
pub enum LogLevel {
    Error = 0,
    Warn = 1,
    Info = 2,
    Debug = 3,
    Trace = 4,
}

Log verbosity level (ordered from least to most verbose).

Variants

Error = 0

Only critical errors are printed.

Warn = 1

Warnings and errors (default).

Info = 2

Informational messages, warnings, and errors.

Debug = 3

Verbose debug output.

Trace = 4

Maximum verbosity — internal trace messages.

Implementations

impl LogLevel

pub fn from_name(s: &str) -> Option<Self>

Parse a string level name (case-insensitive).

Returns None for unrecognised strings. For the standard, fallible str::parse form, use the FromStr implementation.

Example

use tenflowers::logging::LogLevel;

assert_eq!(LogLevel::from_name("info"),  Some(LogLevel::Info));
assert_eq!(LogLevel::from_name("DEBUG"), Some(LogLevel::Debug));
assert_eq!(LogLevel::from_name("???"),   None);

pub fn label(self) -> &'static str

Returns the short upper-case label for this level.

Trait Implementations

impl Clone for LogLevel

fn clone(&self) -> LogLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LogLevel

impl Debug for LogLevel

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

Formats the value using the given formatter.

impl Display for LogLevel

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

Formats the value using the given formatter.

impl Eq for LogLevel

impl FromStr for LogLevel

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

Parse a level name (case-insensitive); see LogLevel::from_name.

type Err = String

The associated error which can be returned from parsing.

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.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LogLevel

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

Equality operator ==.

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

Inequality operator !=.

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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