}

Error indicating failures when reading and writing data from/to a Storage.

Variants

Io(Error, String)

Tuple Fields

0: Error

1: String

Wrapper of io::Error with resource name for which the error occurred.

Utf8Error(Utf8Error)

Tuple Fields

0: Utf8Error

Wrapper of Utf8Error.

MissingSchema(String)

Tuple Fields

0: String

Indicates that schema for the resource with stored name is missing in resource storage.

MissingData

Indicates that part of the data is missing, e.g. one file of a multi_vector

WrongSignature

Fields

resource_name: String

Resource name for which the error occurred.

diff: String

Diff from the stored schema to the expected schema.

Indicates that the schema stored in resource storage differs from the expected schema.

UnexpectedDataSize

Indicates that the size of the data does not fit to the serialized control size.

When data is serialized to resource storage, a control header is written which, in particular, contains the final size of the whole resource.

TooBig

Fields

resource_name: &'static str

Resource name for which the error occurred.

size: usize

Size of the resource

A resource is too big, e.g. when references by a small number of bits

Missing

A resource / archive is missing completely

Implementations

impl ResourceStorageError
