[][src]Struct bve_native::COption

#[repr(C)]
pub struct COption<T> {
    pub value: T,
    pub exists: bool,
}

C safe wrapper for an Option.

Safety

Reading from the value member is undefined behavior if exists is false. In practice it is zeroed.

Fields

value: T

Actual value inside the option. Reading this is undefined behavior if exists is false.

exists: bool

Flag if the value exists or not.
