Enum RecordError 

#[non_exhaustive]
pub enum RecordError {
    Format {
        part: &'static str,
        message: String,
    },
    Empty {
        field: &'static str,
    },
    TooLong {
        field: &'static str,
        length: usize,
        bound: usize,
    },
    NegativeFencingToken {
        producer_id: i64,

    },
    FencingTokenForm {
        text: String,
    },
}

A failure to build or to decode a coordination state record.

RecordError::Format reports malformed bytes, and its part field names the record part that failed. The other variants report a value that a caller or a record gave, and each names the field it rejects.

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.

Format

The bytes do not match the frozen layout of the record part.

Fields

part: &'static str

The record part the decoder failed on. It is key, registration value, or lease value.

message: String

What the decoder found.

Empty

A role or a member id is the empty string.

Fields

field: &'static str

The field that is empty.

TooLong

A role or a member id is longer than its bound.

Fields

field: &'static str

The field that is too long.

length: usize

The length the caller gave, in bytes.

bound: usize

The maximum length of the field, in bytes.

NegativeFencingToken

A fencing token carries a negative producer id or a negative producer epoch.

Fields

producer_id: i64

The producer id the caller gave.

producer_epoch: i16

The producer epoch the caller gave.

FencingTokenForm

A string does not have the producer_id:producer_epoch form of a fencing token.

Fields

text: String

The string the caller gave.

Trait Implementations

impl Clone for RecordError

fn clone(&self) -> RecordError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RecordError

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

Formats the value using the given formatter.

impl Display for RecordError

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

Formats the value using the given formatter.

impl Eq for RecordError

impl Error for RecordError

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.

impl From<RecordError> for CoordinationError

fn from(source: RecordError) -> Self

Converts to this type from the input type.

impl PartialEq for RecordError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
