Module rustix::backend::io::errno

source ·
Expand description

The rustix Errno type.

This type holds an OS error code, which conceptually corresponds to an errno value.

§Safety

Linux uses error codes in -4095..0; we use rustc attributes to describe this restricted range of values.

Structs§

  • errno—An error code.

Functions§

  • Check for an error from the result of a syscall which encodes a c::c_int on success.
  • Check for an error from the result of a syscall which encodes a c::c_uint on success.
  • Check for an error from the result of a syscall which does not return on success. On success, return the unconsumed raw value.
  • Check for an error from the result of a syscall which encodes a file descriptor on success.
  • Check for an error from the result of a syscall which encodes a u64 on success.
  • Check for an error from the result of a syscall which encodes a usize on success.
  • try_decode_void 🔒
    Check for an error from the result of a syscall which encodes no value on success. On success, return the unconsumed raw value.
  • Check for an error from the result of a syscall which encodes a *mut c_void on success.
