System call return variants defined as defined in TRD-Riscv64bit.

These variants correspond to those defined in the core kernel’s SyscallReturn enum. For documentation on the individual variants, refer to that type instead.

Trait Implementations

impl Clone for TRDRiscv64bitSyscallReturn

fn clone(&self) -> TRDRiscv64bitSyscallReturn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TRDRiscv64bitSyscallReturn

impl Debug for TRDRiscv64bitSyscallReturn

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

Formats the value using the given formatter.

impl From<SyscallReturn> for TRDRiscv64bitSyscallReturn

fn from(syscall_return: SyscallReturn) -> Self

Map from the kernel’s SyscallReturn enum to the subset of return values specified in TRD-Riscv64bit. This ensures backwards compatibility with architectures implementing the ABI as specified in the TRD.
