Enum Error 

pub enum Error {
    Http(Error),
    Decode(Error),
    Api {
        code: String,
        message: String,
        status: u16,
    },
    Auth(String),
    Config(String),
    InvalidSignature,
    Url(ParseError),
    Token(String),
}

Crate-level error type.

Variants

Http(Error)

Underlying HTTP transport error (network, timeout, TLS, etc.).

Decode(Error)

Failed to decode a JSON response body.

Api

A bKash API call returned a non-success envelope (i.e. errorCode was present, or statusCode was not "0000").

Fields

code: String

The bKash errorCode (or externalCode for refund responses).

message: String

The human-readable error message from bKash.

status: u16

The HTTP status code returned alongside the body.

Auth(String)

Authentication / authorization failure (e.g. 2001 Invalid App Key, or repeated 401 after a force-regrant).

Config(String)

The client was built with an invalid configuration.

InvalidSignature

Webhook signature verification failed.

Url(ParseError)

Failed to parse a URL.

Token(String)

The token grant / refresh endpoint returned an error.

Implementations

impl Error

pub fn is_transient(&self) -> bool

Returns true if this error represents a transient condition that may succeed on retry (network error, HTTP 5xx, or errorCode == "503").

pub fn is_auth(&self) -> bool

Returns true if this error represents a credential / authorization failure that warrants clearing the token cache and re-granting.

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

Converts to this type from the input type.

impl From<ParseError> for Error

fn from(source: ParseError) -> Self

Converts to this type from the input type.
