Enum ProxyError 

pub enum ProxyError {
    NotFound(String),
    Unauthenticated(String),
    PermissionDenied(String),
    OutOfScope(String),
    InvalidArgument(String),
    PreconditionFailed(String),
    RangeNotSatisfiable(String),
    PayloadTooLarge(String),
    NotImplemented(&'static str),
    Storage(Error),
    Internal(String),
}

Available on crate feature server only.

An error from a storage-proxy operation.

Each variant maps to a fixed HTTP status via IntoResponse. The response body is a small JSON envelope ({ "error": <message> }); the wasm client keys off the status code, not the body.

Variants

NotFound(String)

The requested object or securable does not exist. → 404.

Unauthenticated(String)

The caller is not authenticated. → 401.

PermissionDenied(String)

The caller is authenticated but not permitted for this verb/securable. → 403.

OutOfScope(String)

The request addresses a key outside the securable’s authorized scope (confused-deputy guard). → 403.

InvalidArgument(String)

The request is malformed (bad securable, unparsable header, If-Match: *). → 400.

PreconditionFailed(String)

A conditional write’s If-Match did not match the current object. → 412.

RangeNotSatisfiable(String)

The requested byte range cannot be satisfied. → 416.

PayloadTooLarge(String)

A PUT body exceeded the in-proxy buffering cap for a conditional write. → 413.

NotImplemented(&'static str)

The requested functionality is not implemented (e.g. GCP credential vending in the local arm). → 501.

Storage(Error)

An outcome from the underlying object store. Mapped to a status by matching the object_store::Error variant (see ProxyError::storage_parts).

Internal(String)

An unexpected internal failure. → 500.

Trait Implementations

impl Debug for ProxyError

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

Formats the value using the given formatter.

impl Display for ProxyError

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

Formats the value using the given formatter.

impl Error for ProxyError

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<Error> for ProxyError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl IntoResponse for ProxyError

fn into_response(self) -> Response

Create a response.
