Enum Error 

#[non_exhaustive]
pub enum Error {
    InvalidAcct(String),
    InvalidUrl(ParseError),
    MissingSubject,
    SubjectMismatch {
        requested: String,
        returned: String,
    },
    MissingActorLink,
    Http(Error),
    BadStatus(u16),
    ResponseTooLarge(u64),
    Json(Error),
}

All failure modes for crate.

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.

InvalidAcct(String)

The input string was not a valid acct: URI.

InvalidUrl(ParseError)

A URL could not be parsed.

MissingSubject

The WebFinger response had no subject.

SubjectMismatch

The WebFinger subject did not match the requested resource.

Fields

requested: String

The resource URI that was requested.

returned: String

The resource URI returned by the server.

MissingActorLink

The WebFinger response did not include an ActivityPub actor link.

Http(Error)

Available on crate feature client only.

An HTTP transport error during client resolution.

BadStatus(u16)

Available on crate feature client only.

The server responded with a non-success status.

ResponseTooLarge(u64)

Available on crate feature client only.

The server’s response body exceeded the configured body cap before it could be fully read.

This is a DoS guard: a malicious or compromised WebFinger responder could otherwise stream gigabytes of JSON into the client and exhaust memory.

Json(Error)

The response body could not be parsed as JSON.

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, __formatter: &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.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ParseError> for Error

fn from(source: ParseError) -> Self

Converts to this type from the input type.
