Implementations

impl TRD104SyscallReturn

pub fn from_syscall_return(syscall_return: SyscallReturn) -> Self

Map from the kernel’s SyscallReturn enum to the subset of return values specified in TRD104. This ensures backwards compatibility with architectures implementing the ABI as specified in TRD104.

Trait Implementations

impl Clone for TRD104SyscallReturn

fn clone(&self) -> TRD104SyscallReturn

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TRD104SyscallReturn

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

Formats the value using the given formatter.
