Crate axerrno

Error code definition used by ArceOS.

It provides two error types and the corresponding result types:

• AxError and AxResult: A generic error type similar to std::io::ErrorKind.
• LinuxError and LinuxResult: Linux specific error codes defined in errno.h. It can be converted from AxError.

Macros

• ax_err
  Convenience method to construct an Err(AxError) type while printing a warning message.
• ax_err_type
  Convenience method to construct an AxError type while printing a warning message.
• ensure
  Ensure a condition is true. If it is not, return from the function with an error.

Enums

• AxError
  The error type used by ArceOS.
• LinuxError
  Linux specific error codes defined in errno.h.

Functions

• from_ret_code
  Convents isize into AxResult<usize>
• to_ret_code
  Convents AxResult<usize> into isize, so that it can be transferred in trap contexts

Type Definitions

• AxResult
  A specialized Result type with AxError as the error type.
• LinuxResult
  A specialized Result type with LinuxError as the error type.
