Struct slog::LevelFilter

pub struct LevelFilter<D: Drain> {
    // some fields omitted
}

Record log level filter

Wraps a drain and passes records to it, only if their level is at least given level.

TODO: Remove this type. This drain is a special case of Filter, but because Filter can not use static dispatch ATM due to Rust limitations that will be lifted in the future, it is a standalone type.

Methods

impl<D: Drain> LevelFilter<D>

fn new(drain: D, level: Level) -> Self

Create LevelFilter

Trait Implementations

impl<D: Drain> Drain for LevelFilter<D>

fn log(&self, buf: &mut Vec<u8>, info: &Record, logger_values: &OwnedKeyValueList) -> Result<()>

Write one logging record As an optimization (avoiding allocations), loggers are responsible for providing a byte buffer, that Drain can use for their own needs.
