[−][src]Struct pyo3_log::Logger
The Logger
The actual Logger
that can be installed into the Rust side and will send messages over to
Python.
It can be either created directly and then installed, passed to other aggregating log systems,
or the init
or try_init
functions may be used if defaults are good enough.
Implementations
impl Logger
[src]
pub fn new(py: Python, caching: Caching) -> PyResult<Self>
[src]
Creates a new logger.
It defaults to having a filter for Debug
.
pub fn install(self) -> Result<ResetHandle, SetLoggerError>
[src]
Installs this logger as the global one.
When installing, it also sets the corresponding maximum level, constructed using the filters in this logger.
pub fn reset_handle(&self) -> ResetHandle
[src]
Provides the reset handle of this logger.
Note that installing the logger also returns a reset handle. This function is available if, for example, the logger will be passed to some other logging system that connects multiple loggers together.
pub fn filter(self, filter: LevelFilter) -> Self
[src]
Configures the default logging filter.
Log messages will be filtered according a filter. If one provided by a
filter_target
matches, it takes preference. If none matches,
this one is used.
The default filter if none set is Debug
.
pub fn filter_target(self, target: String, filter: LevelFilter) -> Self
[src]
Sets a filter for a specific target, overriding the default.
This'll match targets with the same name and all the children in the module hierarchy. In case multiple match, the most specific one wins.
With this configuration, modules will log in the following levels:
Logger::default() .filter(LevelFilter::Warn) .filter_target("xy".to_owned(), LevelFilter::Debug) .filter_target("xy::aa".to_owned(), LevelFilter::Trace);
whatever
=>Warn
xy
=>Debug
xy::aa
=>Trace
xy::aabb
=>Debug
