Syscall error codes using POSIX-standard numeric values.

Kernel encodes -(error_code as isize) in the return register (a0). User space decodes negative values back into SysError variants.

Implementations

impl SysError

pub fn as_code(self) -> u16

Returns the error code for this error.

pub fn from_code(code: u16) -> Self

Decodes an error code into a SysError variant.

Trait Implementations

impl Clone for SysError

fn clone(&self) -> SysError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SysError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for SysError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SysError

fn eq(&self, other: &SysError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
