Expand description

Enum of possible argument of the protocol

Variants

Int(i32)

Tuple Fields

0: i32

An integer argument. Represented by a i32.

Uint(u32)

Tuple Fields

0: u32

An unsigned integer argument. Represented by a u32.

Fixed(i32)

Tuple Fields

0: i32

A signed fixed point number with 1/256 precision

Str(Box<CString>)

Tuple Fields

0: 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(Id)

Tuple Fields

0: Id

Id of a wayland object

NewId(Id)

Tuple Fields

0: Id

Id of a newly created wayland object

Array(Box<Vec<u8>>)

Tuple Fields

0: Box<Vec<u8>>

Vec

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(RawFd)

Tuple Fields

0: RawFd

A file descriptor argument. Represented by a RawFd.

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait. Read more
