Enum ResourceStorageError

#[non_exhaustive]
pub enum ResourceStorageError {
    Io(Error, String),
    Utf8Error(Utf8Error),
    MissingSchema(String),
    MissingData,
    WrongSignature {
        resource_name: String,
        diff: String,
    },
    UnexpectedDataSize,
    TooBig {
        resource_name: &'static str,

    },
    Missing,
}

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

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.

Io(Error, String)

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

Utf8Error(Utf8Error)

Wrapper of Utf8Error.

MissingSchema(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

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

Fields

resource_name: String

Resource name for which the error occurred.

diff: String

Diff from the stored schema to 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

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

Fields

resource_name: &'static str

Resource name for which the error occurred.

size: usize

Size of the resource

Missing

A resource / archive is missing completely

Implementations

impl ResourceStorageError

pub fn from_io_error(err: Error, resource_name: String) -> Self

Wraps an io::Error with additional resource name.

Trait Implementations

impl Debug for ResourceStorageError

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

Formats the value using the given formatter.

impl Display for ResourceStorageError

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

Formats the value using the given formatter.

impl Error for ResourceStorageError

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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.
