Struct Logger 

pub struct Logger { /* private fields */ }

A handle for writing messages to a specific log backend.

Core follows a “no global mutable state” architecture. Callers that require a non-default logging backend must create a Logger instance and use it directly.

By default, macros like alog_info! use a platform-appropriate default logger (LogBackend::Android on Android, LogBackend::Stderr otherwise).

Implementations

impl Logger

pub fn new(backend: LogBackend) -> Self

Create a new logger with the specified backend.

pub fn log(&self, level: LogLevel, tag: &str, msg: &str)

Write a message to the logger’s active backend.

Release-mode level stripping is applied here, matching the free log function (CORE-M14): a caller-built Logger must not bypass the documented release strip and let Verbose..Warn — including attacker-controlled strings — reach the backend in release builds.
