log
#中文
the fast log . This crate uses #! [forbid(unsafe_code)] to ensure everything is implemented in 100% Safe Rust.
A log implementation for extreme speed, using Crossbeam/channel ,once Batch write logs,fast log date, Appender architecture, appender per thread
-
Low overhead, based on thread
-
High performance, use lockless message queue, log is stored in queue, then flush disk. It does not block the caller
-
Full APPEND mode file writing, high efficiency for solid state/mechanical disk (solid state and mechanical disk sequential write performance is better than random write)
-
When channel pressure increases, logs can be written in batches at a time
-
Built-in ZIP compression, compressed file name date + serial number, no need to worry about the log file is too large
-
Built-in log segmentation, custom log full number of immediately split
-
Built-in filtering configuration support, can be customized to filter out other library printed logs
-
Support custom compression algorithms, such as ZIP and LZ4
-
Support use
log::logger().flush()
method wait to flush disk -
Simple and efficient Appender architecture.Both configuration and customization are simple

How fast is?
//MACOS(Apple M1MAX-32GB)
Time: 221.079ms ,each:221 ns/op
QPS: 4523139 Iter/s
support Future mode,async await based on mpsc channel, tokio or async_std support log split,zip_compress
- how to use?
= "0.4"
= { = "1.5"}
or enable zip/lz4/gzip Compression library
= "0.4"
# "lz4","zip","gzip"
= { = "1.5" , = ["lz4","zip","gzip"]}
