Trait Implementations

impl Clone for QLGeneratorInterfaceStruct

fn clone(&self) -> QLGeneratorInterfaceStruct

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QLGeneratorInterfaceStruct

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

Formats the value using the given formatter.

impl Encode for QLGeneratorInterfaceStruct

Available on crate feature objc2 only.

const ENCODING: Encoding

The Objective-C type-encoding for this type.

impl PartialEq for QLGeneratorInterfaceStruct

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

impl RefEncode for QLGeneratorInterfaceStruct

Available on crate feature objc2 only.

const ENCODING_REF: Encoding

The Objective-C type-encoding for a reference of this type.

impl Copy for QLGeneratorInterfaceStruct

impl StructuralPartialEq for QLGeneratorInterfaceStruct
