Struct ffi_convert::CRange

#[repr(C)]pub struct CRange<T> {
    pub start: T,
    pub end: T,
}

A utility type to represent range. Note that the parametrized type T should have have CReprOf and AsRust trait implementated.

Example

use ffi_convert::{CReprOf, AsRust, CDrop, CRange};
use std::ops::Range;

#[derive(Clone, Debug, PartialEq)]
pub struct Foo {
    pub range: Range<i32>
}

#[derive(AsRust, CDrop, CReprOf, Debug, PartialEq)]
#[target_type(Foo)]
pub struct CFoo {
    pub range: CRange<i32>
}

let foo = Foo {
    range: Range {
        start: 20,
        end: 30,
    }
};

let c_foo = CFoo {
    range: CRange {
        start: 20,
        end: 30,
    }
};

let c_foo_converted = CFoo::c_repr_of(foo.clone()).unwrap();
assert_eq!(c_foo, c_foo_converted);

let foo_converted = c_foo.as_rust().unwrap();
assert_eq!(foo_converted, foo);

Fields

start: T

end: T
