Struct cxx_qt_lib::QString

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

Binding to Qt QString.

Invariants

As an invariant of this API and the static analysis of the cxx::bridge macro, in Rust code we can never obtain a QString by value. Qt’s QString requires a move constructor and may hold internal pointers, which is not compatible with Rust’s move behavior. Instead in Rust code we will only ever look at a QString through a reference or smart pointer, as in &QString or UniquePtr<QString>.

Implementations

impl QString

pub fn new<T: Private>() -> Self

QString is not constructible via new. Instead, use the let_qstring! macro.

pub fn to_rust(&self) -> String

Create a new Rust string from this QString. This operation needs to convert the UTF-16 data in the QString to UTF-8 data and thus likely needs to an allocate. This is essentially a copy and so any changes will not propagate to the QString.

Trait Implementations

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 = Opaque

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

impl From<&'_ QString> for String

fn from(qstring: &QString) -> Self

Performs the conversion.
