Struct QString

#[repr(C)]
pub struct QString { /* private fields */ }

The QString class provides a Unicode character string.

Note that QString is a UTF-16 whereas Rust strings are a UTF-8

impl<'a> QString

pub fn prepend(&'a mut self, str: &QString) -> &'a mut QString

Prepends the string str to the beginning of this string and returns a reference to this string.

impl<'a> QString

pub fn remove( &'a mut self, str: &QString, cs: CaseSensitivity, ) -> &'a mut QString

Removes every occurrence of the given str string in this string, and returns a reference to this string.

Returns true if the string starts with s; otherwise returns false.

impl QString

pub fn to_html_escaped(&self) -> QString

Converts a plain text string to an HTML string with HTML metacharacters <, >, &, and “ replaced by HTML entities.

impl QString

pub fn arg(&self, a: &QString) -> Self

Returns a copy of this string with the lowest numbered place marker replaced by string a, i.e., %1, %2, …, %99.

pub fn compare(&self, other: &QString, cs: CaseSensitivity) -> Ordering

Lexically compares this string with the other string and returns if this string is less than, equal to, or greater than the other string.

pub fn index_of(&self, str: &QString, from: isize, cs: CaseSensitivity) -> isize

Trait Implementations

impl Add for QString

type Output = QString

The resulting type after applying the + operator.

fn add(self, other: Self) -> Self

Performs the + operation.

impl Clone for QString

fn clone(&self) -> Self

Constructs a copy of other.

This operation takes constant time, because QString is implicitly shared. This makes returning a QString from a function very fast. If a shared instance is modified, it will be copied (copy-on-write), and that takes linear time.

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

Performs copy-assignment from source.

impl Debug for QString

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

Formats the value using the given formatter.

impl Default for QString

fn default() -> Self

Constructs a null string. Null strings are also empty.

impl Display for QString

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

Convert the QString to a Rust string

Note that this converts from UTF-16 to UTF-8

impl Drop for QString

fn drop(&mut self)

Destroys the string.

impl ExternType for QString

type Id = (Q, S, t, r, i, n, g)

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 QString> for QAnyStringView<'a>

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

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

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.

impl PartialOrd for QString

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool
