General application error type

Variants

Network(Error)

Network error from reqwest

Io(Error)

I/O error

Json(Error)

JSON serialization or deserialization error

Unexpected(StatusCode)

Unexpected HTTP status code

Db(Error)

Database error from sqlx

Unauthorized

Unauthorized access error

OAuthTokenExpired

OAuth token expired error (requires token refresh)

NotFound

Resource not found error

RateLimitExceeded

API rate limit exceeded

HistoricalDataAllowanceExceeded

Historical data allowance exhausted (weekly quota of data points)

The allowance_expiry field indicates the number of seconds until the allowance resets. Retrying before that is pointless.

Fields

allowance_expiry: u64

Seconds until the weekly allowance resets

SerializationError(String)

Error during serialization or deserialization

WebSocketError(String)

WebSocket communication error

Deserialization(String)

Deserialization error with details

InvalidInput(String)

Invalid input error with a description of the constraint violated

Generic(String)

Generic error for cases that don’t fit other categories

Trait Implementations

impl Debug for AppError

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

Formats the value using the given formatter.

impl Display for AppError

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

Formats the value using the given formatter.

impl Error for AppError

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.
