Enum Error 

pub enum Error {
    Unauthorized {
        url: String,
        body: String,
    },
    Http {
        status: u16,
        url: String,
        body: String,
    },
    Network(Error),
    Decode {
        url: String,
        source: Error,
    },
    StateMismatch {
        actual: Option<String>,
        expected: String,
    },
    Cancelled(String),
    Timeout(Duration),
    BadRequest(String),
    Io(Error),
}

All errors surfaced by the crate.

Variants

Unauthorized

The platform returned 401. Split out from Error::Http so consumers can render a tailored “sign in again” message instead of the raw response body — the right remedy is almost always “mint a fresh token”, and the body alone ({"error":"unauthenticated"}) doesn’t tell the user that.

Fields

url: String

body: String

Http

The platform returned a non-2xx status (other than 401, which has its own Error::Unauthorized variant). body is truncated to a reasonable size before being attached.

Fields

status: u16

url: String

body: String

Network(Error)

Underlying transport failure (DNS, TLS, connection reset, …).

Decode

The response body wasn’t valid JSON for the expected shape.

Fields

url: String

source: Error

StateMismatch

The OAuth callback returned a state value that didn’t match what we generated. Refusing the token is the only safe move.

Fields

actual: Option<String>

expected: String

Cancelled(String)

The user (or the platform) cancelled the OAuth flow in the browser. The String carries the platform-supplied reason.

Timeout(Duration)

The OAuth handshake didn’t complete within the allotted time.

BadRequest(String)

Caller-side problem — usually a malformed input (e.g. a token that contains bytes we can’t put in an HTTP header).

Io(Error)

Local I/O failure (loopback bind, socket read/write, …).

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
