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

Creates a LogSpecBuilder with all logging turned off.

Creates a LogSpecBuilder from given module filters.

Adds a default log level filter, or updates the default log level filter.

Adds a log level filter, or updates the log level filter, for a module.

Adds a log level filter, or updates the log level filter, for a module.

Adds log level filters from a LogSpecification.

Creates a log specification without text filter.

Creates a log specification with text filter.

This method is only avaible if the dafault feature textfilter is not switched off.

Creates a log specification without being consumed.

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.

Use this to upcast a trait to one of its supertraits. Read more

Use this to cast from one trait object type to another. This method is more customizable than the dyn_cast method. Here you can also specify the “source” trait from which the cast is defined. This can for example allow using casts from a supertrait of the current trait object. Read more
