Struct ConnectionType

#[repr(transparent)]
pub struct ConnectionType {
    pub repr: i32,
}

This enum describes the types of connection that can be used with signals.

Note that UniqueConnection is not supported.

Fields

repr: i32

Implementations

impl ConnectionType

pub const AutoConnection: ConnectionType

If the receiver lives in the thread that emits the signal, Qt::DirectConnection is used. Otherwise, Qt::QueuedConnection is used. The connection type is determined when the signal is emitted.

pub const DirectConnection: ConnectionType

The slot is invoked immediately when the signal is emitted. The slot is executed in the signalling thread.

pub const QueuedConnection: ConnectionType

The slot is invoked when control returns to the event loop of the receiver’s thread. The slot is executed in the receiver’s thread.

pub const BlockingQueuedConnection: ConnectionType

Same as Qt::QueuedConnection, except that the signalling thread blocks until the slot returns. This connection must not be used if the receiver lives in the signalling thread, or else the application will deadlock.

Trait Implementations

impl Clone for ConnectionType

fn clone(&self) -> ConnectionType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ExternType for ConnectionType

type Kind = Trivial

Either cxx::kind::Opaque or cxx::kind::Trivial.

type Id

A type-level representation of the type’s C++ namespace and type name.

impl PartialEq for ConnectionType

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