Struct cxx_qt_lib::QString

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

Expand description

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 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.
