Enum ShareStoreError 

#[non_exhaustive]
pub enum ShareStoreError {
    AlreadyExists {
        channel_id: u64,
        version: u32,
    },
    NotFound {
        channel_id: u64,
        version: u32,
    },
    Backend(Box<dyn Error + Send + Sync + 'static>),
}

Errors produced by DeRecShareStore implementations.

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.

AlreadyExists

A share for (channel_id, version) already exists.

Returned by DeRecShareStore::save when the implementation enforces immutability of versioned share slots. The protocol treats each (channel_id, version) pair as write-once; overwriting a confirmed share is a protocol violation.

Fields

channel_id: u64

version: u32

NotFound

No share was found for (channel_id, version).

Implementations that prefer an explicit error over returning Ok(None) may return this variant from DeRecShareStore::load.

Fields

channel_id: u64

version: u32

Backend(Box<dyn Error + Send + Sync + 'static>)

An I/O or serialization error in the underlying storage backend.

The original error is preserved as the source so that callers can inspect the full error chain via std::error::Error::source.

Trait Implementations

impl Debug for ShareStoreError

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

Formats the value using the given formatter.

impl Display for ShareStoreError

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

Formats the value using the given formatter.

impl Error for ShareStoreError

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<ShareStoreError> for Error

fn from(source: ShareStoreError) -> Self

Converts to this type from the input type.
