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, H> LevelSplitWriter<L, H>

where L: MakeWriter, H: MakeWriter,

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

New split writer with default WARN threshold.

pub fn threshold(self, threshold: Severity) -> LevelSplitWriter<L, H>

Override the threshold.
