Enum Error 

#[non_exhaustive]
pub enum Error {
    Http(Error),
    Json(Error),
    Io(Error),
    Api {
        errcode: i32,

All errors produced by this SDK.

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.

Http(Error)

HTTP transport error.

Json(Error)

JSON serialization/deserialization error.

Io(Error)

File I/O error.

Api

Server returned a non-zero error code.

Fields

errcode: i32

Server error code.

errmsg: String

Server error message.

TokenStale

Bot token is stale; the poll loop has entered its cooldown window.

Only long polling is paused — outbound calls are not blocked by the SDK.

SessionExpired

👎Deprecated since 0.3.0:

use Error::TokenStale

Deprecated: use Error::TokenStale.

CdnUpload(String)

CDN upload failure.

Crypto(String)

AES encryption/decryption failure.

Config(String)

Invalid configuration.

Timeout(String)

Operation timed out.

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
