Enum Error 

#[non_exhaustive]
pub enum Error {
    Sqlite(Error),
    Json(Error),

Everything that can go wrong inside grit-core.

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)

Underlying SQLite failure.

Json(Error)

Op or attribute JSON failed to (de)serialize.

Io(Error)

Filesystem failure (export/import).

Closed

The writer actor has shut down; the handle is unusable.

NotFound(Uuid)

A referenced node/edge/episode does not exist.

InvalidHlc(String)

A stored HLC string failed to parse.

SchemaTooNew

The database schema version is newer than this library understands. Migrations are forward-only (Design Invariant 8).

Fields

found: i64

PRAGMA user_version found in the file.

supported: i64

Latest version this build can open.

InvalidOp(String)

An op is structurally invalid (e.g. merging a node into itself).

Embedding(String)

Embedding operations before register_embedding_model, or a dimension mismatch against the registered model.

Import(String)

An import line could not be understood.

Corrupt(String)

A stored row failed to decode (e.g. a malformed uuid) — the database contains data grit did not write. Surfaced loudly rather than silently dropping the row.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
