Represents the different ways converting from SAFEARRAY can fail

Variants

SafeArrayDimsInvalid

Either the safe array dimensions = 0 or > 1 multi-dimensional arrays are not handled.

Fields of SafeArrayDimsInvalid

sa_dims: u32

safe array dimensions that was wrong

VarTypeDoesNotMatch

Expected vartype did not match found vartype - runtime consistency check

Fields of VarTypeDoesNotMatch

expected: u32	The expected vartype
found: u32	the found vartype

SafeArrayLBoundFailed

Call to SafeArrayGetLBound failed

Fields of SafeArrayLBoundFailed

hr: i32

HRESULT returned

SafeArrayRBoundFailed

Call to SafeArrayGetRBound failed

Fields of SafeArrayRBoundFailed

hr: i32

HRESULT returned

SafeArrayGetVartypeFailed

Call to SafeArrayGetVartype failed

Fields of SafeArrayGetVartypeFailed

hr: i32

HRESULT returned

ElementConversionFailed

Encapsulates the ElementError that occurred during conversion

Fields of ElementConversionFailed

index: usize	the index the conversion failed at
element: Box<ElementError>	The element error encapsulating the failure

Methods

impl FromSafeArrayError

pub fn from_element_err<E: Into<ElementError>>(     ee: E,     index: usize ) -> FromSafeArrayError

converts an ElementError into a FromSafeArrayError Need the index so a From impl doesn't apply

Trait Implementations

impl Debug for FromSafeArrayError

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl From<FromSafeArrayError> for SafeArrayError

fn from(fsae: FromSafeArrayError) -> SafeArrayError

Performs the conversion.
