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)

Underlying HTTP transport failure.

Json(Error)

JSON decoding failure.

Url(ParseError)

URL parsing failure.

Status

Yahoo returned a non-success status code.

Fields

status: u16

HTTP status code.

message: String

Best-effort message extracted from the response body.

Yahoo

Yahoo’s chart/v8 endpoint returned an explicit error payload.

Fields

symbol: String

Symbol that triggered the error.

code: String

Yahoo error code (e.g. Not Found).

description: String

Human-readable description.

RateLimited

We got a 429 from Yahoo and exhausted retry budget.

Auth(String)

Could not obtain an authenticated session (cookie + crumb).

TickerMissing

The ticker symbol is missing or delisted.

Fields

ticker: String

The requested symbol.

reason: String

Reason supplied by the upstream API or our parser.

TimezoneMissing(String)

The ticker has no timezone info — usually means delisted.

PricesMissing

No price data returned for the requested period/interval.

Fields

ticker: String

The requested symbol.

hint: String

Human-readable hint about why data was missing.

InvalidPeriod

The requested period/interval combination is not allowed.

Fields

ticker: String

The requested symbol.

reason: String

Why the combination is invalid.

UnexpectedResponse(String)

A response field had an unexpected shape.

InvalidArgument(String)

A required argument was invalid.

Io(Error)

Catch-all for unexpected I/O.

Implementations

impl Error

pub fn unexpected(msg: impl Display) -> Self

Construct an Error::UnexpectedResponse with a formatted message.

pub fn invalid(msg: impl Display) -> Self

Construct an Error::InvalidArgument with a formatted message.

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
