Struct std::os::windows::io::NullHandleError
pub struct NullHandleError(/* private fields */);
Available on Windows only.
This is the error type used by HandleOrNull when attempting to convert into a handle, to indicate that the value is null.
Trait Implementations
impl Clone for NullHandleErrorfn clone(&self) -> NullHandleError
Returns a copy of the value. Read more
fn clone_from(&mut self, source: &Self)
Performs copy-assignment from
source. Read more
impl Debug for NullHandleErrorfn fmt(&self, f: &mut Formatter<'_>) -> Result
Formats the value using the given formatter. Read more
impl Display for NullHandleErrorfn fmt(&self, fmt: &mut Formatter<'_>) -> Result
Formats the value using the given formatter. Read more
impl Error for NullHandleErrorfn source(&self) -> Option<&(dyn Error + 'static)>
The lower-level source of this error, if any. Read more
fn description(&self) -> &str👎Deprecated since 1.42.0: use the Display impl or to_string()
fn cause(&self) -> Option<&dyn Error>👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
fn provide<'a>(&'a self, request: &mut Request<'a>)🔬This is a nightly-only experimental API. (
error_generic_member_access #99301)
Provides type based access to context intended for error reports. Read more
impl PartialEq for NullHandleErrorfn eq(&self, other: &NullHandleError) -> 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.

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>
Performs the conversion.
