Implementations§

source§

impl HRESULT

source

pub fn is_err(&self) -> bool

source§

impl HRESULT

source

pub fn result(self) -> Result<()>

Turns an HRESULT from the COM crate::ffi API declaration into a Result containing HassleError.

source

pub fn result_with_success<T>(self, v: T) -> Result<T>

Turns an HRESULT from the COM crate::ffi API declaration into a Result containing HassleError, with the desired value.

Note that v is passed by value and is not a closure that is executed lazily. Use the short-circuiting ? operator for such cases:

let mut blob: ComPtr<IDxcBlob> = ComPtr::new();
unsafe { self.inner.get_result(blob.as_mut_ptr()) }.result()?;
Ok(DxcBlob::new(blob))
