pub enum GlibNoneOrInvalidError<I: Error> {
    Invalid(I),
    None,
}

None

Implementations

impl<I: Error> GlibNoneOrInvalidError<I>

pub fn none() -> Self

Builds the None variant.

pub fn is_none(&self) -> bool

Returns true if self is the None variant.

pub fn is_invalid(&self) -> bool

Returns true if self is the Invalid variant.

Trait Implementations

impl<I: Debug + Error> Debug for GlibNoneOrInvalidError<I>

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

Formats the value using the given formatter.

impl<I: Error> Display for GlibNoneOrInvalidError<I>

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

Formats the value using the given formatter.

impl<I: Error> Error for GlibNoneOrInvalidError<I>

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

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)

Provides type based access to context intended for error reports.

impl<I: Error> From<I> for GlibNoneOrInvalidError<I>

fn from(invalid: I) -> Self

Converts to this type from the input type.

impl<I: PartialEq + Error> PartialEq for GlibNoneOrInvalidError<I>

fn eq(&self, other: &GlibNoneOrInvalidError<I>) -> 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.
