Tuple Fields

0: i32

Implementations

impl HRESULT

pub const fn is_ok(self) -> bool

Returns true if self is a success code.

pub const fn is_err(self) -> bool

Returns true if self is a failure code.

pub fn unwrap(self)

Asserts that self is a success code.

This will invoke the panic! macro if self is a failure code and display the HRESULT value for diagnostics.

pub fn ok(self) -> Result<(), Error>

Converts the HRESULT to Result<()>.

pub fn map<F, T>(self, op: F) -> Result<T, Error>

where F: FnOnce() -> T,

Calls op if self is a success code, otherwise returns HRESULT converted to Result<T>.

pub fn and_then<F, T>(self, op: F) -> Result<T, Error>

where F: FnOnce() -> Result<T, Error>,

Calls op if self is a success code, otherwise returns HRESULT converted to Result<T>.

pub fn message(self) -> String

The error message describing the error.

pub fn from_thread() -> HRESULT

Creates a new HRESULT from the Win32 error code returned by GetLastError().

impl Ord for HRESULT

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for HRESULT

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

Equality operator ==.

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