Struct Logger 

pub struct Logger<W: Write + Send> { /* private fields */ }

Represents a logging object that writes to a specified output. It can be used simultaneously from multiple threads; it guarantees to serialize writes.

Use LoggerBuilder to construct a Logger, or use Logger::default().

Implementations

impl<W: Write + Send> Logger<W>

pub fn builder(w: W) -> LoggerBuilder<W>

Returns a LoggerBuilder that can be used to build a Logger.

pub fn write_output( &self, level: Level, target: &str, file: Option<&str>, line: Option<u32>, s: &str, )

Writes the given string s using the logger. Typically, you would not use this directly but instead use the macros provided by the log crate.

fn default() -> Logger<Stderr>

A default Logger has

• level: log::LevelFilter::Trace,
• out: stderr,
• flags: L_STD, and
