Enum Error 

pub enum Error {
    InvalidIri(String),
    Request(String, RequestError),
    Status(String, u16),
    MediaType(String, Option<String>),
    NotAContext(String),
    Load(String, String),
    Kv(KvError),
    TooMany(usize),
    TimedOut,
    JsonLd(Error),
}

Why a context could not be loaded, or a document’s contexts resolved.

Variants

InvalidIri(String)

The IRI is not an http or https URL.

Request(String, RequestError)

The request was refused or failed: a private address, a response past MAX_CONTEXT_BYTES, a network failure.

Status(String, u16)

The server answered other than 200.

MediaType(String, Option<String>)

The server answered with a type other than MEDIA_TYPE.

NotAContext(String)

What came back is not a JSON object with an @context member.

Load(String, String)

The application’s loader failed.

Kv(KvError)

The key-value store failed. fetch_cached reports a failing store to its caller rather than failing with this.

TooMany(usize)

The document named more contexts to load than Limits::max_remote.

TimedOut

Loading took longer than Limits::timeout.

JsonLd(Error)

The document cannot be expanded.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
