Enum ResourceHandle

pub enum ResourceHandle {
    Fd(ResourceHandleFd),
    Socket(ResourceHandleSocket),
}

Represents an underlying handle for a platform. On unix, everything is an fd. On Windows, everything is a Windows handle except for sockets (which are SOCKETs).

Variants

Fd(ResourceHandleFd)

A file handle/descriptor.

Socket(ResourceHandleSocket)

A socket handle/file descriptor.

Implementations

impl ResourceHandle

pub fn from_fd_like(io: &impl AsRawFd) -> Self

Converts a file-like thing to a ResourceHandle.

pub fn from_socket_like(io: &impl AsRawFd) -> Self

Converts a socket-like thing to a ResourceHandle.

pub fn is_valid(&self) -> bool

Runs a basic validity check on the handle, but cannot fully determine if the handle is valid for use.

pub fn as_fd_like(&self) -> Option<ResourceHandleFd>

Returns this as a file-descriptor-like handle.

pub fn as_socket_like(&self) -> Option<ResourceHandleSocket>

Returns this as a socket-like handle.

pub fn is_terminal(&self) -> bool

Determines if this handle is a terminal. Analagous to std::io::IsTerminal.

Trait Implementations

impl Clone for ResourceHandle

fn clone(&self) -> ResourceHandle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResourceHandle

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

Formats the value using the given formatter.

impl Hash for ResourceHandle

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ResourceHandle

fn eq(&self, other: &ResourceHandle) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
