Struct qt_core::QCollatorSortKey

#[repr(C)]
pub struct QCollatorSortKey { /* fields omitted */ }

The QCollatorSortKey class can be used to speed up string collation.

C++ class: QCollatorSortKey.

C++ documentation:

The QCollatorSortKey class can be used to speed up string collation.

The QCollatorSortKey class is always created by QCollator::sortKey() and is used for fast strings collation, for example when collating many strings.

Methods

impl QCollatorSortKey

pub unsafe fn compare(&self, key: impl CastInto<Ref<QCollatorSortKey>>) -> c_int

Compares the key to otherKey. Returns a negative value if the key is less than otherKey, 0 if the key is equal to otherKey or a positive value if the key is greater than otherKey.

Calls C++ function: int QCollatorSortKey::compare(const QCollatorSortKey& key) const.

C++ documentation:

Compares the key to otherKey. Returns a negative value if the key is less than otherKey, 0 if the key is equal to otherKey or a positive value if the key is greater than otherKey.

See also operator<().

pub unsafe fn copy_from(
    &mut self,
    other: impl CastInto<Ref<QCollatorSortKey>>
) -> MutRef<QCollatorSortKey>

Assigns other to this collator key.

Calls C++ function: QCollatorSortKey& QCollatorSortKey::operator=(const QCollatorSortKey& other).

C++ documentation:

Assigns other to this collator key.

pub unsafe fn new_copy(
    other: impl CastInto<Ref<QCollatorSortKey>>
) -> CppBox<QCollatorSortKey>

Constructs a copy of the other collator key.

Calls C++ function: [constructor] void QCollatorSortKey::QCollatorSortKey(const QCollatorSortKey& other).

C++ documentation:

Constructs a copy of the other collator key.

pub unsafe fn swap(&mut self, other: impl CastInto<MutRef<QCollatorSortKey>>)

Swaps this collator key with other.

Calls C++ function: void QCollatorSortKey::swap(QCollatorSortKey& other).

C++ documentation:

Swaps this collator key with other.
