Enum FetchError 

pub enum FetchError {
    Request(RequestError),
    Signing(String),
    Redirect(String),
    Status(u16),
    NotActivityPub(String),
    Invalid(String),
    NoId,
    CrossOrigin {
        id: String,
        url: Url,
    },
    ForeignAuthor {
        id: String,
        author: String,
    },
    Read(ReadError),
    Portable(Vec<(String, String)>),
}

Why a fetch did not produce a document.

Variants

Request(RequestError)

The request was not answered, or was refused before it was sent.

Signing(String)

The request could not be signed.

Redirect(String)

A redirect could not be followed: too many, no Location, or from https to http.

Status(u16)

The server answered with a status other than success.

NotActivityPub(String)

The response is not ActivityPub; the content type it had.

Invalid(String)

The response is not a JSON object.

NoId

The document has no id.

CrossOrigin

The document’s id is not on the origin it was served from, and nothing else vouches for it.

Fields

id: String

url: Url

ForeignAuthor

The document names an author, in attributedTo or actor, on another origin than its own id: its server cannot vouch that the author wrote it.

Fields

id: String

author: String

Read(ReadError)

The document was established but is not a value of the type asked for.

Portable(Vec<(String, String)>)

No gateway served a portable object whose proof holds; why, for each gateway tried.

Implementations

impl FetchError

pub fn status(&self) -> Option<u16>

The status the server answered with, if it answered with one other than success. A 404 or 410 says the object is gone.

Trait Implementations

impl Debug for FetchError

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

Formats the value using the given formatter.

impl Display for FetchError

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

Formats the value using the given formatter.

impl Error for FetchError

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<FetchError> for ResolveError

fn from(error: FetchError) -> Self

Converts to this type from the input type.

impl From<RequestError> for FetchError

fn from(error: RequestError) -> Self

Converts to this type from the input type.
