Errors for converting from C/C++ data structure to Rust types

Variants

GetElementFailed

Fields

hr: i32

Holds an HRESULT value

The unsafe call to SafeArrayGetElement failed - HRESULT stored within tells why

BStringFailed(Box<BStringError>)

Holds a BStringError in a box.

FromVarError(Box<FromVariantError>)

[from_variant] failed somehow. Error is stored in a box.

Trait Implementations

impl Debug for FromSafeArrElemError

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

Formats the value using the given formatter.

impl Display for FromSafeArrElemError

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

Formats the value using the given formatter.

impl Fail for FromSafeArrElemError

fn name(&self) -> Option<&str>

Returns the “name” of the error.

fn cause(&self) -> Option<&dyn Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

fn backtrace(&self) -> Option<&Backtrace>

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D>where D: Display + Send + Sync + 'static, Self: Sized,

Provides context for this failure.

fn compat(self) -> Compat<Self>where Self: Sized,

Wraps this failure in a compatibility wrapper that implements std::error::Error.

impl From<FromSafeArrElemError> for ElementError

fn from(fsaee: FromSafeArrElemError) -> ElementError

Holds a FromSafeArrElemError with a box. This means conversion is free.

impl From<FromVariantError> for FromSafeArrElemError

fn from(fve: FromVariantError) -> FromSafeArrElemError

Boxes a FromVariantError into a FromSafeArrElemError which means the conversion is free.
