Enum LogLevel

pub enum LogLevel {
    Debug = 1,
    Error = 4,
    Info = 2,
    Trace = 0,
    Warn = 3,
    Off = -1,
}

Variants

Debug = 1

the debug designation (rank 1) often used for development

Error = 4

the error designation (rank 4) is used for errors that are not fatal to the program

Info = 2

the info designation (rank 2) is used for useful information

Trace = 0

the trace designation (rank 0) is used for very low-level (often extremely verbose) information

Warn = 3

The warn designation (rank 3)

Off = -1

the off designation (rank -1) is used to turn off logging

where __H: Hasher,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

impl IntoEnumIterator for LogLevel

type Iterator = LogLevelIter

fn iter() -> LogLevelIter

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
