Struct otter::prelude::flexi_logger::LogSpecBuilder
[−]pub struct LogSpecBuilder { /* private fields */ }
Expand description
Builder for LogSpecification
.
Example
Start with a programmatically built log specification, and use the
LoggerHandle
to apply a modified version of the log specification
at a later point in time:
use flexi_logger::{Logger, LogSpecification};
use log::LevelFilter;
fn main() {
// Build the initial log specification
let mut builder = LogSpecification::builder();
builder
.default(LevelFilter::Info)
.module("karl", LevelFilter::Debug);
// Initialize Logger, keep builder alive
let mut logger = Logger::with(builder.build())
// your logger configuration goes here, as usual
.start()
.unwrap_or_else(|e| panic!("Logger initialization failed with {}", e));
// ...
// Modify builder and update the logger
builder
.default(LevelFilter::Error)
.remove("karl")
.module("emma", LevelFilter::Trace);
logger.set_new_spec(builder.build());
// ...
}
Implementations
impl LogSpecBuilder
impl LogSpecBuilder
pub fn new() -> LogSpecBuilder
pub fn new() -> LogSpecBuilder
Creates a LogSpecBuilder
with all logging turned off.
pub fn from_module_filters(module_filters: &[ModuleFilter]) -> LogSpecBuilder
pub fn from_module_filters(module_filters: &[ModuleFilter]) -> LogSpecBuilder
Creates a LogSpecBuilder
from given module filters.
pub fn default(&mut self, lf: LevelFilter) -> &mut LogSpecBuilder
pub fn default(&mut self, lf: LevelFilter) -> &mut LogSpecBuilder
Adds a default log level filter, or updates the default log level filter.
pub fn module<M>(
&mut self,
module_name: M,
lf: LevelFilter
) -> &mut LogSpecBuilder where
M: AsRef<str>,
pub fn module<M>(
&mut self,
module_name: M,
lf: LevelFilter
) -> &mut LogSpecBuilder where
M: AsRef<str>,
Adds a log level filter, or updates the log level filter, for a module.
pub fn remove<M>(&mut self, module_name: M) -> &mut LogSpecBuilder where
M: AsRef<str>,
pub fn remove<M>(&mut self, module_name: M) -> &mut LogSpecBuilder where
M: AsRef<str>,
Adds a log level filter, or updates the log level filter, for a module.
pub fn insert_modules_from(
&mut self,
other: LogSpecification
) -> &mut LogSpecBuilder
pub fn insert_modules_from(
&mut self,
other: LogSpecification
) -> &mut LogSpecBuilder
Adds log level filters from a LogSpecification
.
pub fn finalize(self) -> LogSpecification
pub fn finalize(self) -> LogSpecification
Creates a log specification without text filter.
pub fn finalize_with_textfilter(self, tf: Regex) -> LogSpecification
pub fn finalize_with_textfilter(self, tf: Regex) -> LogSpecification
Creates a log specification with text filter.
This method is only avaible if the dafault feature textfilter
is not switched off.
pub fn build(&self) -> LogSpecification
pub fn build(&self) -> LogSpecification
Creates a log specification without being consumed.
pub fn build_with_textfilter(&self, tf: Option<Regex>) -> LogSpecification
pub fn build_with_textfilter(&self, tf: Option<Regex>) -> LogSpecification
Creates a log specification without being consumed, optionally with a text filter.
This method is only avaible if the dafault feature textfilter
is not switched off.
