Enum Level 

pub enum Level {
    Trace = 0,
    Debug = 1,
    Info = 2,
    Warning = 3,
    Error = 4,
    Fatal = 5,
    Panic = 6,
}

Log level definition.

Loggers evaluates these in descending order, so f.ex. a log level of Level::Info includes Level::Warning and Level::Panic, but not Level::Debug.

Variants

Trace = 0

Used for tracing code execution path; updates at this level get additional built-in attributes such as logger ID, caller filename and line number. Rasant will also log trace updates for some operations, such as sink additions and log level changes.

Debug = 1

Messages useful for debugging and troubleshooting.

Info = 2

Normal operation updates.

Warning = 3

Unusual events that might require attention, but do not otherwise impact normal operation.

Error = 4

Error updates.

Fatal = 5

Appplication-wide errors from which recovery is impoosible.

Panic = 6

Similar to Level::Fatal, but the application panics right after logging the update.

Implementations

impl Level

pub fn value(&self) -> u8

Returns a numeric value for the log level.

pub fn covers(&self, other: &Level) -> bool

Evaluates whether this level covers another - i.e. it’s at the same, or higher level.

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

Evaluates whether this level is covered by another.

pub fn color(&self) -> Color

Returns a color associated with a given level, useful mostly for pretty printing.

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

Returns a name for the level.

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

Returns a full uppercase name for the level.

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

Returns a short, three-letter name for the level.

pub fn syslog_severity(&self) -> u16

Returns a syslog severity for the level.
