Struct DirectSockOptReadOnly

Source 
pub struct DirectSockOptReadOnly<T>(/* private fields */);
Expand description

Implementation of just GetSockOpt with fixed level and optname values, similar to DirectSockOpt but for read-only options.

Trait Implementations§

Source§

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

Source§

type OptVal = T

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

type Result = T

The type of the result of the getsockopt call.
Source§

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).
Source§

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

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