Enum CorrectionError 

pub enum CorrectionError {
    InsufficientShards {
        needed: usize,
        available: usize,
    },
    HmacMismatch {
        index: u8,
    },
    ReedSolomonError {
        reason: String,
    },
    InvalidParameters {
        reason: String,
    },
}

Errors produced by the error-correction bounded context.

Variants

InsufficientShards

Too few shards survive to reconstruct the original data.

Fields

needed: usize

Minimum number of data shards required.

available: usize

Number of valid shards available.

HmacMismatch

An HMAC tag did not match the shard contents.

Fields

index: u8

Zero-based shard index whose tag failed validation.

ReedSolomonError

The Reed-Solomon library reported an unrecoverable error.

Fields

reason: String

Human-readable reason for the failure.

InvalidParameters

Shard set parameters are invalid (e.g. zero data shards).

Fields

reason: String

Human-readable reason the parameters are invalid.

Trait Implementations

impl Debug for CorrectionError

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

Formats the value using the given formatter.

impl Display for CorrectionError

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

Formats the value using the given formatter.

impl Error for CorrectionError

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<CorrectionError> for AppError

fn from(source: CorrectionError) -> Self

Converts to this type from the input type.
