Trait cxx::vector::VectorElement[−][src]

pub unsafe trait VectorElement: Sized { }
Expand description

Trait bound for types which may be used as the T inside of a CxxVector<T> in generic code.

This trait has no publicly callable or implementable methods. Implementing it outside of the CXX codebase is not supported.

Example

A bound T: VectorElement may be necessary when manipulating CxxVector in generic code.

use cxx::vector::{CxxVector, VectorElement};
use std::fmt::Display;

pub fn take_generic_vector<T>(vector: &CxxVector<T>)
where
    T: VectorElement + Display,
{
    println!("the vector elements are:");
    for element in vector {
        println!("  • {}", element);
    }
}

Writing the same generic function without a VectorElement trait bound would not compile.
