Enum BlobStoreError 

#[non_exhaustive]
pub enum BlobStoreError {
    NotFound(String),
    PermissionDenied(String),
    InvalidInput(String),
    PayloadTooLarge(String),
    Io(String),
    Unsupported(String),
    Signature(String),
    Backend(String),
}

Errors returned by BlobStore operations.

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.

NotFound(String)

The requested key was not found.

PermissionDenied(String)

Authentication or authorization failed against the backend.

InvalidInput(String)

Invalid input — most often a malformed or unsafe key.

PayloadTooLarge(String)

Caller exceeded a backend size limit (per-file or per-request). Maps to HTTP 413 Payload Too Large.

Io(String)

I/O failure (filesystem, network, transport).

Unsupported(String)

The configured backend doesn’t support this operation.

Signature(String)

A signed URL could not be verified or has expired.

Backend(String)

Backend-specific error reported as a string for portability.

Implementations

impl BlobStoreError

pub fn io(err: impl Display) -> Self

Wrap an io::Error for the I/O variant.

pub fn backend(err: impl Display) -> Self

Convenience constructor for BlobStoreError::Backend.

impl BlobStoreError

pub const fn status(&self) -> StatusCode

HTTP status code that best fits this error variant.

pub fn into_autumn_error(self) -> AutumnError

Promote into an AutumnError carrying the status from BlobStoreError::status.

Handlers using ? get a 500 by default via the blanket impl From<E: Error> for AutumnError; call this instead to preserve the precise status (404 for missing blobs, 403 for signature failures, etc.).

Trait Implementations

impl Debug for BlobStoreError

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

Formats the value using the given formatter.

impl Display for BlobStoreError

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

Formats the value using the given formatter.

impl Error for BlobStoreError

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<BlobStoreError> for VariantError

fn from(source: BlobStoreError) -> Self

Converts to this type from the input type.
