Variants

WritePastSpan

Write exceeded the declared span length.

Fields

span: u64

Declared span length.

written: u64

Bytes written so far.

ChunkTooLarge

Chunk data exceeds maximum allowed size.

Fields

max: usize

Maximum allowed size.

actual: usize

Actual size.

Store(Box<dyn Error + Send + Sync>)

Chunk store failed to store a chunk.

Getter(Box<dyn Error + Send + Sync>)

Chunk getter failed to retrieve a chunk.

InvalidReference

Invalid chunk reference encountered during tree traversal.

Fields

level: usize

Tree level where the invalid reference was found.

ChunkNotFound(ChunkAddress)

Required chunk was not found.

SpanMismatch

Span value doesn’t match expected value.

Fields

expected: u64

Expected span value.

actual: u64

Actual span value.

Chunk(ChunkError)

Underlying chunk error.

Encryption(EncryptionError)

Encryption error.

InvalidEntryRef

Invalid entry reference length (expected 32 or 64 bytes).

Fields

len: usize

Actual byte length of the reference.

InvalidChunkType

Expected a content chunk but got a different chunk type.

Fields

type_name: &'static str

Name of the chunk type that was received.

Implementations

impl FileError

pub fn store<E: Error + Send + Sync + 'static>(err: E) -> Self

Create a store error from any error type.

pub fn getter<E: Error + Send + Sync + 'static>(err: E) -> Self

Create a getter error from any error type.

Trait Implementations

impl Debug for FileError

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

Formats the value using the given formatter.

impl Display for FileError

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

Formats the value using the given formatter.

impl Error for FileError

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<EncryptionError> for FileError

fn from(source: EncryptionError) -> Self

Converts to this type from the input type.

impl From<FileError> for PrimitivesError

fn from(source: FileError) -> Self

Converts to this type from the input type.
