pub struct Silent;Expand description
A no-op (no-operation) implementation of LoggerImpl.
SilentLogger satisfies the logger interface while effectively discarding all
log messages. This is useful for:
- Testing: Disabling log output during unit tests.
- Defaults: Providing a safe, “do-nothing” fallback logger.
- Performance: Avoiding conditional “if logger.is_some()” checks in hot paths.
Implementations§
Source§impl Silent
impl Silent
Sourcepub fn new() -> Box<Self>
pub fn new() -> Box<Self>
Creates a new, heap-allocated instance of SilentLogger.
This is a convenience constructor that returns the logger inside a Box,
making it directly compatible with Logger::new().
§Example
let logger = Logger::new(SilentLogger::new());Trait Implementations§

Source§fn status(&self) -> LoggerStatus
fn status(&self) -> LoggerStatus
Always returns LoggerStatus::Running.
Since the SilentLogger cannot fail in its mission to do nothing, it
is perpetually in a healthy state.
Source§fn log(&self, _message: Message)
fn log(&self, _message: Message)
Discards the incoming Message immediately.
This method is essentially a “black hole.” The underscore in _message
ensures the compiler does not warn about the unused variable while
the message is dropped at the end of the scope.
Source§fn as_any(&self) -> &dyn Any
fn as_any(&self) -> &dyn Any
Returns the SilentLogger instance as a [dyn Any].
