fast_log v1.6.1 Release Notes

Main Updates

• Added zero-copy mmap file logging for better performance under high load.

• Introduced MmapFile struct to implement mmap file logging. It implements the FilePlugin interface.

• Users can configure MmapFile for mmap logging via the split option:

Need to enable features = ["mmap"] in Cargo.toml to use mmap.

split::<MmapFile, LogPacker>(
    "target/logs/mmap.log",
    LogSize::MB(10),
    RollingType::Size,
    LogPacker{}, 
)

• MmapFile supports rolling files by size or time.

• Standard file logging still available, both can be used together.

• Optimized performance and resource usage of logging.

Usage Notes

• Require Rust 1.70 or above.

• Need to enable features = ["mmap"] in Cargo.toml to use mmap.

• MmapFile works on Linux, Windows, OSX etc.

• Avoid too large file size when rolling by size to limit memory use.

• Still use standard IO to read logs, mmap reading not recommended.

Full Changelog

• feat: add mmap file logging
• feat: new MmapFile struct
• docs: update docs and examples
• refactor: optimize core logging path
• test: more tests
• chore: upgrade dependencies etc.
