Struct QAnyStringView

#[repr(C)]
pub struct QAnyStringView<'a> { /* private fields */ }

The QAnyStringView class provides a unified view of a Latin-1, UTF-8, or UTF-16 string.

Implementations

impl QAnyStringView<'_>

pub fn is_empty(&self) -> bool

Returns true if the string has no characters; otherwise returns false.

impl QAnyStringView<'_>

pub fn is_null(&self) -> bool

Returns true if this string is null; otherwise returns false.

impl QAnyStringView<'_>

pub fn to_qstring(&self) -> QString

Returns a deep copy of this string view’s data as a QString.

impl QAnyStringView<'_>

pub fn len(&self) -> isize

Returns the number of characters in this string.

Trait Implementations

impl<'a> Clone for QAnyStringView<'a>

fn clone(&self) -> QAnyStringView<'a>

Constructs a copy of other.

This operation takes constant time, because QAnyStringView is a view-only string.

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

Performs copy-assignment from source.

impl Default for QAnyStringView<'_>

fn default() -> Self

Constructs a null string. Null strings are also empty.

impl ExternType for QAnyStringView<'_>

type Id = (Q, A, n, y, S, t, r, i, n, g, V, i, e, w)

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

type Kind = Trivial

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

impl<'a> From<&'a QByteArray> for QAnyStringView<'a>

fn from(bytes: &'a QByteArray) -> Self

Constructs a QAnyStringView from a QByteArray

impl<'a> From<&'a QString> for QAnyStringView<'a>

fn from(string: &'a QString) -> Self

Constructs a QAnyStringView from a QString

impl<'a> From<&'a str> for QAnyStringView<'a>

fn from(str: &'a str) -> Self

Constructs a QAnyStringView from a Rust string

impl PartialEq for QAnyStringView<'_>

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