Struct wasmtime_wiggle::tracing::metadata::LevelFilter [−][src]
#[repr(transparent)]pub struct LevelFilter(_);
Expand description
A filter comparable to a verbosity Level
.
If a Level
is considered less than a LevelFilter
, it should be
considered disabled; if greater than or equal to the LevelFilter
, that
level is enabled.
Note that this is essentially identical to the Level
type, but with the
addition of an OFF
level that completely disables all trace
instrumentation.
Implementations
impl LevelFilter
[src]
impl LevelFilter
[src]pub const OFF: LevelFilter
[src]
pub const OFF: LevelFilter
[src]The “off” level.
Designates that trace instrumentation should be completely disabled.
pub const ERROR: LevelFilter
[src]
pub const ERROR: LevelFilter
[src]The “error” level.
Designates very serious errors.
pub const WARN: LevelFilter
[src]
pub const WARN: LevelFilter
[src]The “warn” level.
Designates hazardous situations.
pub const INFO: LevelFilter
[src]
pub const INFO: LevelFilter
[src]The “info” level.
Designates useful information.
pub const DEBUG: LevelFilter
[src]
pub const DEBUG: LevelFilter
[src]The “debug” level.
Designates lower priority information.
pub const TRACE: LevelFilter
[src]
pub const TRACE: LevelFilter
[src]The “trace” level.
Designates very low priority, often extremely verbose, information.
pub const fn from_level(level: Level) -> LevelFilter
[src]
pub const fn from_level(level: Level) -> LevelFilter
[src]Returns a LevelFilter
that enables spans and events with verbosity up
to and including level
.
pub const fn into_level(self) -> Option<Level>
[src]
pub const fn into_level(self) -> Option<Level>
[src]pub fn current() -> LevelFilter
[src]
pub fn current() -> LevelFilter
[src]Returns a LevelFilter
that matches the most verbose Level
that any
currently active Subscriber
will enable.
User code should treat this as a hint. If a given span or event has a
level higher than the returned LevelFilter
, it will not be enabled.
However, if the level is less than or equal to this value, the span or
event is not guaranteed to be enabled; the subscriber will still
filter each callsite individually.
Therefore, comparing a given span or event’s level to the returned
LevelFilter
can be used for determining if something is
disabled, but should not be used for determining if something is
enabled.`
