Enum StoreError 

#[non_exhaustive]
pub enum StoreError {
    Sqlite(Error),
    Io(Error),
    Json(Error),
    SchemaMismatch {
        found: String,
        expected: &'static str,
    },
    MissingMetadata(String),
    Corrupt(&'static str),
    Closed,
}

An error from building or opening a persisted corpus.

The Corpus read methods are infallible by trait contract — a Store validates its schema and metadata at Store::open, so subsequent reads degrade to empty results rather than surfacing an error. This type covers only the fallible build and open steps.

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.

Sqlite(Error)

A SQLite operation failed.

Io(Error)

A filesystem operation failed.

Json(Error)

A feature row could not be serialized to JSON.

SchemaMismatch

The opened store’s schema version is not the one this build understands.

Fields

found: String

The schema version stored in the file.

expected: &'static str

The schema version this build writes and reads.

MissingMetadata(String)

A required metadata fact was absent from the opened store.

Corrupt(&'static str)

A stored metadata value was present but unparseable.

Closed

The builder was used after it had already been published.

Trait Implementations

impl Debug for StoreError

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

Formats the value using the given formatter.

impl Display for StoreError

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

Formats the value using the given formatter.

impl Error for StoreError

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.
