Enum DurationError

#[non_exhaustive]
pub enum DurationError {
    OutOfRange,
    MismatchedSigns,
    Deserialize(Box<dyn Error + Send + Sync>),
}

Represent failures in converting or creating Duration instances.

Examples

let duration = Duration::new(Duration::MAX_SECONDS + 2, 0);
assert!(matches!(duration, Err(DurationError::OutOfRange)));

let duration = Duration::new(0, 1_500_000_000);
assert!(matches!(duration, Err(DurationError::OutOfRange)));

let duration = Duration::new(120, -500_000_000);
assert!(matches!(duration, Err(DurationError::MismatchedSigns)));

let ts = Duration::try_from("invalid");
assert!(matches!(ts, Err(DurationError::Deserialize(_))));

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

OutOfRange

One of the components (seconds and/or nanoseconds) was out of range.

MismatchedSigns

The sign of the seconds component does not match the sign of the nanoseconds component.

Deserialize(Box<dyn Error + Send + Sync>)

Cannot deserialize the duration.

Trait Implementations

impl Debug for DurationError

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

Formats the value using the given formatter.

impl Display for DurationError

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

Formats the value using the given formatter.

impl Error for DurationError

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

Returns 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.
