Struct zvariant::Fd

pub struct Fd(_);

A RawFd wrapper.

See also OwnedFd if you need a wrapper that takes ownership of the file.

We wrap the RawFd type so that we can implement Serialize and Deserialize for it. File descriptors are serialized in a special way and you need to use specific serializer and deserializer API when file descriptors are or could be involved.

Trait Implementations

impl AsRawFd for Fd

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl Basic for Fd

const SIGNATURE_CHAR: char = 'h'

The type signature, as a character.

const SIGNATURE_STR: &'static str = _

The type signature, as a string.

fn alignment(format: EncodingFormat) -> usize

The required padding alignment for the given format.

impl Clone for Fd

fn clone(&self) -> Fd

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Fd

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Fd

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where
    D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Fd

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

Formats the value using the given formatter.

impl<'a> From<&'a Fd> for Value<'a>

fn from(v: &'a Fd) -> Self

Converts to this type from the input type.

impl<T> From<&T> for Fdwhere
    T: AsRawFd,

fn from(t: &T) -> Self

Converts to this type from the input type.

impl<'a> From<Fd> for OwnedValue

fn from(v: Fd) -> Self

Converts to this type from the input type.

impl<'a> From<Fd> for Value<'a>

fn from(v: Fd) -> Self

Converts to this type from the input type.

impl From<i32> for Fd

fn from(value: RawFd) -> Self

Converts to this type from the input type.

impl Hash for Fd

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<Fd> for Fd

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Fd

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>where
    S: Serializer,

Serialize this value into the given Serde serializer.
