Trait fern::IntoLog [−] [src]

pub trait IntoLog {
    fn into_fern_logger(self) -> Result<Box<Logger>>;
    fn into_log(self) -> Result<Box<Log>>;
}

Trait which represents any logger configuration which can be built into a fern::Logger or log::Log.

Required Methods

fn into_fern_logger(self) -> Result<Box<Logger>>

Builds this configuration into a fern::Logger that you can send messages to. This method can be used to generate a logger you can call manually, and catch any errors from. You probably want to use fern::init_global_logger() instead of calling this directly.

fn into_log(self) -> Result<Box<Log>>

Builds this configuration into a log::Log that you can send messages to. This will open any files, get handles to stdout/stderr, etc. depending on which type of logger this is.
