Logger

Struct Logger 

Source
pub struct Logger;
Available on crate feature terminal only.
Expand description

Initializes the process logger from the shared log flags.

Implementations§

Source§

impl Logger

Source

pub fn try_init(log: &LogFlags) -> Result<()>

Initialises env_logger from log. When LogFlags::file is set the log target is opened in append mode (creating it if missing) and used for output; otherwise logs go to stderr as usual.

Opening the log file is fallible: if the caller asked for one but we cannot create or open it, the error is returned rather than silently falling back to stderr and polluting interactive prompts.
