An OANDA client failure.

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.

Invariant(&'static str)

The client’s internal admission state is inconsistent.

InvalidInput(String)

Local input or environment is invalid.

RateLimited

Local query or stream capacity was exhausted.

ProviderRateLimited

Provider rate limited a request.

ProviderRateLimitedInvariant

HTTP 429 proves refusal, but the shared cooldown could not be installed.

Fields

source: Box<Error>

The admission invariant failure, retained alongside the definitive status.

Provider

The provider rejected the request definitively.

Fields

status: u16

HTTP response status.

code: Option<String>

OANDA’s errorCode, when it supplied a readable one.

message: Option<String>

OANDA’s errorMessage, when it supplied a readable one.

AmbiguousMutation

An I/O or decode outcome leaves a mutation uncertain.

Fields

account: AccountID

Affected account identifier.

ReconciliationRequired

This account requires explicit reconciliation before another mutation.

Fields

account: AccountID

Affected account identifier.

MutationInFlight

Another mutation for this account is still in flight.

Fields

account: AccountID

Affected account identifier.

Transport(String)

Transport failed before a response was available.

ResponseTooLarge

The response or stream record exceeds a configured bound.

IncompleteStreamRecord

A finite buffered cut ended inside an unterminated stream record.

Fields

bytes: usize

Bytes remaining after the last complete newline-delimited record.

StreamAlreadyEnded

The stream had ended before a buffered cut could be established.

Decode(String)

Provider response did not match the documented shape.

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<R> From<Error> for OperationError<R>

fn from(source: Error) -> Self

Converts to this type from the input type.
