olio 1.4.0

Miscellaneous I/O utilities


Rustdoc Change Log crates.io CI Status

Provides I/O-related utilities complimenting the Rust Standard Library std::io, std::fs, etc.

  • The fs module includes a PosRead trait, offering a uniform pread for positioned file reads; and a ReadSlice supporting multiple independent reader instances limited to a fixed start..end range.

  • The io module includes a GatheringReader, which presents a continuous Read interface over N non-contiguous byte buffers.

  • The mem module includes a MemHandle supporting prioritized concurrent memory access advice (e.g. madvise (2) on unix).

Minimum supported rust version

MSRV := 1.39.0

The crate will fail fast on any lower rustc (via a build.rs version check) and is also CI tested on this version.
