Struct env_logger::filter::Filter [−][src]
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
impl Filter
[src]
pub fn filter(&self) -> LevelFilter
[src]
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);
pub fn matches(&self, record: &Record<'_>) -> bool
[src]
Checks if this record matches the configured filter.
pub fn enabled(&self, metadata: &Metadata<'_>) -> bool
[src]
Determines if a log message with the specified metadata would be logged.
