Trait Implementations

impl Clone for QVariantMap

fn clone(&self) -> QVariantMap

Returns a copy of the value.

impl Default for QVariantMap

fn default() -> QVariantMap

Returns the “default value” for a type.

impl Drop for QVariantMap

fn drop(&mut self)

Executes the destructor for this type.

impl<K, V, const N: usize> From<[(K, V); N]> for QVariantMap

where K: Into<QString>, V: Into<QVariant>,

fn from(m: [(K, V); N]) -> QVariantMap

Converts to this type from the input type.

impl<K, V> From<HashMap<K, V>> for QVariantMap

where K: Into<QString>, V: Into<QVariant>,

fn from(m: HashMap<K, V>) -> QVariantMap

Converts to this type from the input type.

impl<K, V> FromIterator<(K, V)> for QVariantMap

where K: Into<QString>, V: Into<QVariant>,

fn from_iter<I>(iter: I) -> QVariantMap

where I: IntoIterator<Item = (K, V)>,

Creates a value from an iterator.

impl Index<QString> for QVariantMap

fn index(&self, key: QString) -> &<QVariantMap as Index<QString>>::Output

Wrapper around at(int) method.

type Output = QVariant

The returned type after indexing.

impl IndexMut<QString> for QVariantMap

fn index_mut( &mut self, key: QString ) -> &mut <QVariantMap as Index<QString>>::Output

Wrapper around operator[](int) operator method.

impl<'a> IntoIterator for &'a QVariantMap

type Item = (&'a QString, &'a QVariant)

The type of the elements being iterated over.

type IntoIter = QVariantMapIterator<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <&'a QVariantMap as IntoIterator>::IntoIter

Creates an iterator from a value.

impl PartialEq for QVariantMap

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

fn register(_name: Option<&CStr>) -> i32

Registers the type.

fn id() -> i32

fn to_qvariant(&self) -> QVariant

Returns a QVariant containing a copy of this object
