Memory Logger

A logger that stores entries in memory, allowing late and sporadic consumption.

Cargo Documentation


  • Two flavors: blocking and asynchronous.
  • Optional target matching using Regex.
  • Simple design, few dependencies, very fast to compile.
  • No unsafe code.


Both logging and reading use a mutex around a single buffer, and therefore may block. This should be good enough for most scenarios, and has a smaller memory overhead and better locality (single buffer).


Both logging and reading use a channel, and may never block. This should be faster for high contention scenarios, but has a higher memory overhead and worse locality.


Memory logger aims to be a simple logging mechanism. There are no plans to implement advanced features.
