Enum of possible argument types as recognized by the wire

Variants

Int

An integer argument. Represented by a i32.

Uint

An unsigned integer argument. Represented by a u32.

Fixed

A signed fixed point number with 1/256 precision

Str(AllowNull)

A string. This is represented as a CString in a message.

Object(AllowNull)

Id of a wayland object

NewId

Id of a newly created wayland object

Array

Vec

Fd

A file descriptor argument. Represented by a [RawFd].

Implementations

impl ArgumentType

pub fn same_type(self, other: Self) -> bool

Returns true if the type of the argument is the same.

Examples found in repository

src/protocol.rs (line 276)

pub(crate) fn check_for_signature<Id, Fd>(
    signature: &[ArgumentType],
    args: &[Argument<Id, Fd>],
) -> bool {
    if signature.len() != args.len() {
        return false;
    }
    for (typ, arg) in signature.iter().copied().zip(args.iter()) {
        if !arg.get_type().same_type(typ) {
            return false;
        }
    }
    true
}

Trait Implementations

impl Clone for ArgumentType

fn clone(&self) -> ArgumentType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ArgumentType

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

Formats the value using the given formatter.

impl PartialEq<ArgumentType> for ArgumentType

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