Enum GenerateError

An ID could not be generated.

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.

NotInitialized

init has not been called with a node of the type this ID uses.

Fields

node: &'static str

Node type of the ID: u32, or its TypedNode struct.

DefaultGenerator(GeneratorError)

The default node does not fit this ID’s format.

Clock(SystemTimeError)

The system clock could not be read.

ClockBeforeEpoch

The system clock is before the format’s epoch.

Fields

now_unix_millis: u64

Current time, in milliseconds since the Unix epoch.

epoch_unix_millis: u64

The format’s epoch, in milliseconds since the Unix epoch.

ClockRollback

The system clock moved behind the last issued timestamp. Generation resumes on its own once the clock catches up.

Fields

behind_millis: u64

How far the clock is behind the last issued timestamp.

SequenceExhausted

Every sequence number of the current millisecond is used. Retrying on the next millisecond succeeds.

TimestampExhausted

The current time no longer fits the format’s timestamp width.

Trait Implementations

impl Clone for GenerateError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GenerateError

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

Formats the value using the given formatter.

impl Display for GenerateError

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

Formats the value using the given formatter.

impl Error for GenerateError

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.
