Enum Argument 

pub enum Argument<'a, Id> {
    Int(i32),
    Uint(u32),
    Fixed(i32),
    Str(Option<Box<CString>>),
    Object(&'a Id),
    NewId(&'a Id),
    Array(Box<&'a [u8]>),
    Fd(BorrowedFd<'a>),
}

Enum of possible argument of the protocol

Variants

Int(i32)

An integer argument. Represented by a i32.

Uint(u32)

An unsigned integer argument. Represented by a u32.

Fixed(i32)

A signed fixed point number with 1/256 precision

Str(Option<Box<CString>>)

CString

The value is boxed to reduce the stack size of Argument. The performance impact is negligible as string arguments are pretty rare in the protocol.

Object(&'a Id)

Id of a wayland object

NewId(&'a Id)

Id of a newly created wayland object

Array(Box<&'a [u8]>)

Vec<u8>

The value is boxed to reduce the stack size of Argument. The performance impact is negligible as array arguments are pretty rare in the protocol.

Fd(BorrowedFd<'a>)

A file descriptor argument. Represented by a BorrowedFd.

Implementations

impl<'a, Id> Argument<'a, Id>

pub fn get_type(&self) -> ArgumentType

Retrieve the type of a given argument instance

Trait Implementations

impl<'a, Id: Clone> Clone for Argument<'a, Id>

fn clone(&self) -> Argument<'a, Id>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, Id: Debug> Debug for Argument<'a, Id>

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

Formats the value using the given formatter.

impl<'a, Id: Display> Display for Argument<'a, Id>

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

Formats the value using the given formatter.

impl<'a, Id: Eq> Eq for Argument<'a, Id>

impl<'a, Id: PartialEq> PartialEq for Argument<'a, Id>

fn eq(&self, other: &Self) -> 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.
