Struct Logger 

pub struct Logger { /* private fields */ }

A cloneable handle for logging messages.

Logger provides methods for logging at various levels and configuring the logging behavior. It can be freely cloned and shared across threads.

Messages are sent to a background thread for async I/O, so logging calls return immediately without blocking.

Configuration

Use the builder-style methods to configure the logger:

• level(): Set minimum log level
• stdout(): Route output to stdout
• stderr(): Route output to stderr
• file(): Route output to a file

Example

let (logger, handle) = init();
let logger = logger.level(Level::Info).stdout();

logger.info("Starting autonomous");
logger.debug("This won't print because level is Info");

Implementations

impl Logger

pub fn log(&self, level: Level, message: &str)

Logs a message at the given level if it meets the current threshold.

pub fn flush(&self)

Flushes any buffered log output.

pub fn trace(&self, msg: &str)

Logs a trace-level message.

pub fn debug(&self, msg: &str)

Logs a debug-level message.

pub fn info(&self, msg: &str)

Logs an info-level message.

pub fn warn(&self, msg: &str)

Logs a warning-level message.

pub fn error(&self, msg: &str)

Logs an error-level message.

pub fn level(self, level: Level) -> Self

Sets the minimum log level for this logger.

pub fn stdout(self) -> Self

Routes output to stdout.

pub fn stderr(self) -> Self

Routes output to stderr.

pub fn file(self, path: &str) -> Result<Self>

Routes output to a file at the provided path.
