Struct env_logger::filter::Filter

source ·
pub struct Filter { /* private fields */ }
Expand description

A log filter.

This struct can be used to determine whether or not a log record should be written to the output. Use the Builder type to parse and construct a Filter.

Implementations§

source§

impl Filter

source

pub fn filter(&self) -> LevelFilter

Returns the maximum LevelFilter that this filter instance is configured to output.

Example
use log::LevelFilter;
use env_logger::filter::Builder;

let mut builder = Builder::new();
builder.filter(Some("module1"), LevelFilter::Info);
builder.filter(Some("module2"), LevelFilter::Error);

let filter = builder.build();
assert_eq!(filter.filter(), LevelFilter::Info);
source

pub fn matches(&self, record: &Record<'_>) -> bool

Checks if this record matches the configured filter.

source

pub fn enabled(&self, metadata: &Metadata<'_>) -> bool

Determines if a log message with the specified metadata would be logged.
