Why building the blob-declaration model failed.

Variants

MissingColumn

A declared blob column is absent from the table’s live schema.

Fields

table: String

column: String

Sqlite(Error)

A schema read (PRAGMA table_info) failed.

Changeset(ChangesetError)

A captured host changeset could not be read.

InvalidSize

A row’s declared size column is negative.

Fields

table: String

value: i64

MissingHash

A row names a blob but has no content hash.

Fields

table: String

row_id: String

ChangesetWalkMismatch

New and old changeset walks produced different row counts.

Fields

old_count: usize

new_count: usize

MissingPublicationPrimaryKey

A blob-bearing INSERT or UPDATE has no primary key.

Fields

table: String

MissingPublicationRow

The transaction row named by a blob-bearing change is absent.

Fields

table: String

primary_key: String

MissingPublicationBlob

The transaction row named by a blob-bearing change no longer carries a blob.

Fields

table: String

primary_key: String

PublicationBlobMismatch

The transaction row carries a different blob than its change introduced.

Fields

table: String

primary_key: String

changed_blob_id: String

row_blob_id: String

CloudPathNotKeyedByBlob

A Replaceable blob’s readable cloud path does not name the blob it carries, so the row’s next blob would be keyed at this blob’s cloud object and overwrite it. See cloud_path_names_blob.

Fields

table: String

blob_id: String

cloud_path: String

WriteOnceBlobRepointed

A WriteOnce row was repointed at a different blob. Its cloud path is a stable readable name — that is what write-once buys — so the new blob would be keyed at the old blob’s cloud object and overwrite it.

Fields

table: String

blob_id: String

Trait Implementations

impl Debug for BlobDeclError

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

Formats the value using the given formatter.

impl Display for BlobDeclError

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

Formats the value using the given formatter.

impl Error for BlobDeclError

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<BlobDeclError> for DbError

fn from(source: BlobDeclError) -> Self

impl From<BlobDeclError> for SnapshotImageError

fn from(source: BlobDeclError) -> Self

Converts to this type from the input type.

impl From<Error> for BlobDeclError

fn from(e: Error) -> Self
