Trait oaidl::SafeArrayElement

pub trait SafeArrayElement: Sized {
    const SFTYPE: u32;

    fn into_safearray(
        &mut self, 
        psa: *mut SAFEARRAY, 
        ix: i32
    ) -> Result<(), IntoSafeArrElemError>;
    fn from_safearray(
        psa: *mut SAFEARRAY, 
        ix: i32
    ) -> Result<Self, FromSafeArrElemError>;
}

Helper trait implemented for types that can be converted into a safe array. Generally, don't implement this yourself without care. Implemented for types: * i8, u8, i16, u16, i32, u32 * bool, f32, f64 * String, Variant, * Ptr, Ptr

Associated Constants

const SFTYPE: u32

This is the VT value used to create the SAFEARRAY

Required Methods

fn into_safearray(
    &mut self,
    psa: *mut SAFEARRAY,
    ix: i32
) -> Result<(), IntoSafeArrElemError>

puts a type into the safearray at the specified index (default impls use SafeArrayPutElement)

fn from_safearray(
    psa: *mut SAFEARRAY,
    ix: i32
) -> Result<Self, FromSafeArrElemError>

gets a type from the safearray at the specified index (default impls use SafeArrayGetElement)
