Struct cxx_qt_lib::QVariant

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

Expand description

Binding to Qt QVariant.

Invariants

As an invariant of this API and the static analysis of the cxx::bridge macro, in Rust code we can never obtain a QVariant by value. Qt’s QVariant 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 QVariant through a reference or smart pointer, as in &QVariant or UniquePtr<QVariant>.

Implementations

impl QVariant

pub fn to_rust(&self) -> Variant

Create a new Rust Variant from this QVariant. This is a copy operation so any changes will not propagate to the original QVariant.
