Implementations

impl HRESULT

pub fn is_err(&self) -> bool

impl HRESULT

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

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

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))

Trait Implementations

impl Clone for HRESULT

fn clone(&self) -> HRESULT

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HRESULT

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

Formats the value using the given formatter.

impl Display for HRESULT

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

Formats the value using the given formatter.

impl From<i32> for HRESULT

fn from(v: i32) -> Self

Converts to this type from the input type.

impl LowerHex for HRESULT

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

Formats the value using the given formatter.

impl Ord for HRESULT

fn cmp(&self, other: &HRESULT) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for HRESULT

fn eq(&self, other: &HRESULT) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for HRESULT

fn partial_cmp(&self, other: &HRESULT) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
