Struct linux_io::fd::sockopt::DirectSockOpt

pub struct DirectSockOpt<T> { /* private fields */ }

Implementation of both SetSockOpt and GetSockOpt with fixed level and optname values, passing the arg type directly through to the underlying system calls.

Trait Implementations

impl<'a, T: 'a> GetSockOpt<'a> for DirectSockOpt<T>

type OptVal = T

The type that “optval” will be a pointer to in the call.

type Result = T

The type of the result of the getsockopt call.

fn prepare_getsockopt_args(&self) -> (int, int)

Prepare the arguments for a getsockopt system call. The tuple elements of the result are (level, optname, optlen).

fn prepare_getsockopt_result(&self, _: int, optval: T) -> Self::Result

Prepare a raw successful result from a getsockopt call to be returned.

impl<'a, T: 'a> SetSockOpt<'a> for DirectSockOpt<T>

type ExtArg = T

The type that the caller will provide when setting this option.

type OptVal = T

The type that “optval” will be a pointer to in the call.

type Result = i32

The type of the result of the setsockopt call.

fn prepare_setsockopt_args( &self, arg: &Self::ExtArg ) -> (int, int, *const Self::OptVal, socklen_t)

Prepare the arguments for a setsockopt system call. The tuple elements of the result are (level, optname, optval, optlen).

fn prepare_setsockopt_result(&self, raw: int) -> Self::Result

Prepare a raw successful result from a setsockopt call to be returned.
