Struct Error 

pub struct Error(/* private fields */);

Anything a call to the API can fail with.

The type is one pointer wide whatever the failure was, so a Result from this crate is the size of its success value plus a pointer. Match on kind to tell the failures apart; the Display of this type is the sentence to show a user, and source leads to the failure underneath when there was one.

Implementations

impl Error

pub fn kind(&self) -> &ErrorKind

Which kind of failure this is.

Trait Implementations

impl Debug for Error

fn fmt(&self, formatter: &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 StdError + 'static)>

The failure underneath this one, when there is one.

An ErrorKind::Api has none: the server’s answer is the failure, and it is already what Display prints. A response-validation failure leads to the decode error that names the offending field, which carries a position Display leaves out. A connection failure leads to the transport’s own error, which a caller can downcast to - unless it held a credential of the request, when it is a private redacted copy that cannot be downcast.

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<ApiError> for Error

fn from(error: ApiError) -> Self

Converts to this type from the input type.

impl From<ResponseValidationError> for Error

fn from(error: ResponseValidationError) -> Self

Converts to this type from the input type.
