Struct rustix::io::epoll::Owning

pub struct Owning<'context, T: Into<OwnedFd> + From<OwnedFd>> { /* private fields */ }

A type implementing Context where the Data type is T, a type implementing From<OwnedFd> and From<T> for OwnedFd.

This may be used with OwnedFd, or higher-level types like std::fs::File or std::net::TcpStream.

Implementations

impl<'context, T: Into<OwnedFd> + From<OwnedFd>> Owning<'context, T>

pub fn new() -> Self

Creates a new empty Owning.

Trait Implementations

impl<'context, T: AsFd + Into<OwnedFd> + From<OwnedFd>> Context for Owning<'context, T>

type Data = T

The type of an element owned by this context.

type Target = BorrowedFd<'context>

The type of a value used to refer to an element owned by this context.

fn acquire<'call>(&self, data: Self::Data) -> Ref<'call, Self::Target>

Assume ownership of data, and returning a Target.

fn encode(&self, target: Ref<'_, Self::Target>) -> u64

Encode target as a u64. The only requirement on this value is that it be decodable by decode.

unsafe fn decode<'call>(&self, raw: u64) -> Ref<'call, Self::Target>

Decode raw, which is a value encoded by encode, into a Target.

fn release(&self, target: Ref<'_, Self::Target>) -> Self::Data

Release ownership of the value referred to by target and return it.
