errno-codes
Rust library for dealing with errno codes sent over the network from
different operation systems and/or CPU architectures.
Why?
errno is a standard way for handling errors in many standard libraries of
many operating systems. Unfortunately, very few errno constant identifiers
are standardized, and a lot of errno values with the same meaning use
different numeric constants across different OSes.
On Linux, some CPU architectures may define their own numeric constants (see
$KERNEL_SRC/arch/$ARCH/include/uapi/asm/errno.h), different from common
values used by the most of other architectures (see
$KERNEL_SRC/include/uapi/asm-generic/errno*.h). It looks like this was done
for source-level compatibility with proprietary Unixes for these CPU
architectures.
Despite compatibility complications, raw errno codes are sometimes used in
network protocols. This library simplifies working with such protocols.
Known errno codes
Source code with constants and mappings generate automatically based on header files from following OSes:
- Linux, all architectures known by kernel 4.16
- Windows (MinGW)
Usage
Add this to your Cargo.toml:
[dependencies]
errno-codes = "0.1"
See examples/ directory and crate errno-codes-tool for usage examples.
