Enum oauth2::RequestTokenError

#[non_exhaustive]
pub enum RequestTokenError {
    ServerResponse(ErrorResponse),
    Client(Error),
    Parse(Error, Vec<u8>),
    Other(Cow<'static, str>),
}

Error encountered while requesting access token.

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.

ServerResponse(ErrorResponse)

Error response returned by authorization server. Contains the parsed ErrorResponse returned by the server.

Client(Error)

A client error that occured.

Parse(Error, Vec<u8>)

Failed to parse server response. Parse errors may occur while parsing either successful or error responses.

Other(Cow<'static, str>)

Some other type of error occurred (e.g., an unexpected server response).

Trait Implementations

impl Debug for RequestTokenError

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

Formats the value using the given formatter.

impl Display for RequestTokenError

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

Formats the value using the given formatter.

impl Error for RequestTokenError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.41.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
