Enum Error 

pub enum Error {
    Td(error),
    Json(Error),
    Auth(AuthorizationState),
    Cancelled,
    MessageFailed(MessageKey, error),
    MessageDeleted(MessageKey),
    UnexpectedResponse(&'static str),
    Disconnected,
}

An inspectable client failure.

TDLib codes and messages are preserved rather than classified into a library-defined retry policy. This enum does not represent every unsolicited update or native log message.

Variants

Td(error)

TDLib reported an error, preserving its original code and message.

Returned for request failures or delivered as an unsolicited diagnostic through on_error.

Json(Error)

A request could not be serialized or native output could not be decoded.

Auth(AuthorizationState)

The bot helper encountered an authorization state it does not handle.

Cancelled

Token-triggered cleanup won according to the operation’s cancellation rules.

MessageFailed(MessageKey, error)

A tracked send failed; contains its temporary key and the native error.

MessageDeleted(MessageKey)

A tracked temporary message was deleted by a non-cache update.

UnexpectedResponse(&'static str)

The native response did not have the shape required by this operation.

Disconnected

The owner is unavailable, admission is closed, or a reply was abandoned during teardown.

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.
