Module logger

logger.rs Lightweight, feature-gated logger implementation for embedded environments.

This module provides:

• A Logger trait for uniform logging
• A log! macro with debug_log feature gating
• Multiple logger implementations:
  • SerialLogger: For serial output (core::fmt::Write)
  • BufferedLogger: Keeps logs in memory (heapless::String)
  • NoopLogger: Discards all log output

When the debug_log feature is disabled, the log! macro expands to nothing, and all logging calls are removed at compile time.

Example

use dvcdbg::{log, logger::{Logger, SerialLogger}};

struct DummyWriter(String);
impl core::fmt::Write for DummyWriter {
    fn write_str(&mut self, s: &str) -> core::fmt::Result {
        self.0.push_str(s);
        Ok(())
    }
}

let mut dw = DummyWriter(String::new());
let mut logger = SerialLogger::new(&mut dw);
log!(logger, "Hello {}!", "world");
