Expand description
System call return variants defined as defined in TRD104.
These are a strict subset of the variants defined in the core
kernel’s SyscallReturn
enum. For documentation on the
individual variants, refer to this type instead.

Implementations§
Source§impl TRD104SyscallReturn
impl TRD104SyscallReturn
Sourcepub fn from_syscall_return(syscall_return: SyscallReturn) -> Self
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.
