Implementations

impl Builder

pub fn build( &mut self ) -> Box<dyn Fn(&mut Formatter, &Record<'_>) -> Result<()> + Sync + Send>

Convert the format into a callable function.

If the custom_format is Some, then any default_format switches are ignored. If the custom_format is None, then a default format is returned. Any default_format switches set to false won’t be written by the format.

Trait Implementations

impl Default for Builder

fn default() -> Self

Returns the “default value” for a type.
