[−][src]Struct flexi_logger::ReconfigurationHandle
Allows reconfiguring the logger programmatically.
Example
Obtain the ReconfigurationHandle
(using .start()
):
let mut log_handle = Logger::with_str("info") // ... your logger configuration goes here, as usual .start() .unwrap_or_else(|e| panic!("Logger initialization failed with {}", e)); // ...
You can permanently exchange the log specification programmatically, anywhere in your code:
// ... log_handle.parse_new_spec("warn"); // ...
However, when debugging, you often want to modify the log spec only temporarily, for
one or few method calls only; this is easier done with the following method, because
it allows switching back to the previous spec:
log_handle.parse_and_push_temp_spec("trace"); // ... // critical calls // ... log_handle.pop_temp_spec(); // Continue with the log spec you had before. // ...
Methods
impl ReconfigurationHandle
[src]
pub fn set_new_spec(&mut self, new_spec: LogSpecification)
[src]
Replaces the active LogSpecification
.
pub fn parse_new_spec(&mut self, spec: &str)
[src]
Tries to replace the active LogSpecification
with the result from parsing the given String.
pub fn push_temp_spec(&mut self, new_spec: LogSpecification)
[src]
Replaces the active LogSpecification
and pushes the previous one to a Stack.
pub fn parse_and_push_temp_spec(&mut self, new_spec: &str)
[src]
Tries to replace the active LogSpecification
with the result from parsing the given String
and pushes the previous one to a Stack.
pub fn pop_temp_spec(&mut self)
[src]
Reverts to the previous LogSpecification
, if any.
