Struct LevelSplitWriter 

pub struct LevelSplitWriter<L, H> { /* private fields */ }

Composes two writers — INFO+ goes through low, WARN+ through high. The conventional shape for cargo binaries.

Implementations

impl<L: MakeWriter, H: MakeWriter> LevelSplitWriter<L, H>

pub fn new(low: L, high: H) -> Self

New split writer with default WARN threshold.

pub fn threshold(self, threshold: Severity) -> Self

Override the threshold.
