Trait oaidl::SafeArrayExt

pub trait SafeArrayExt<T: SafeArrayElement> {
    fn into_safearray(&mut self) -> Result<Ptr<SAFEARRAY>, SafeArrayError>;
    fn from_safearray(psa: Ptr<SAFEARRAY>) -> Result<Vec<T>, SafeArrayError>;
}

Workhorse trait and main interface for converting to/from SAFEARRAY. Default impl is on ExactSizeIterator<Item=SafeArrayElement>

Required Methods

fn into_safearray(&mut self) -> Result<Ptr<SAFEARRAY>, SafeArrayError>

Use t.into_safearray() to convert a type into a SAFEARRAY

fn from_safearray(psa: Ptr<SAFEARRAY>) -> Result<Vec<T>, SafeArrayError>

Use T::from_safearray(psa) to convert a safearray pointer into the relevant T

Implementors

impl<Itr, Elem> SafeArrayExt<<Itr as Iterator>::Item> for Itrwhere
    Itr: ExactSizeIterator,
    Itr::Item: SafeArrayElement<Element = Elem> + TryConvert<Elem, ElementError>,
    Elem: TryConvert<Itr::Item, ElementError>,

Blanket implementation, requires that TryConvert is implement between Itr::Item and Elem where Elem is the target type for conversion into/from the SAFEARRAY
