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.

NonPositiveOrderSize

An order placement quantity was zero or negative.

NonPositiveReplacementSize

A replacement quantity was zero or negative.

EmptyModification

An order modification contained no replacement values.

NonPositiveBracketTicks

A bracket distance was zero or negative.

UnsupportedOrderType

An order request used an undocumented or unknown provider type code.

Fields

code: i32

Unrecognized provider wire code.

UnsupportedOrderSide

An order request used a provider side code unknown to this crate version.

Fields

code: i32

Unrecognized provider wire code.

UnsupportedOrderStatus

An order query used a provider status code unknown to this crate version.

Fields

code: i32

Unrecognized provider wire code.

NonPositiveOrderPageSize

A v2 order query requested a zero or negative page size.

NegativeOrderPageOffset

A v2 order query requested a negative page offset.

NonPositiveHistoryUnitNumber

A historical-bar unit count was zero or negative.

HistoryLimitOutOfRange

A historical-bar limit exceeded the provider-supported range.

HistoryRangeNotIncreasing

A historical-bar range ended at or before its start.

SearchRangeNotIncreasing

An order or trade search ended at or before its start.

NonPositivePartialCloseSize

A partial-close quantity was zero or negative.

impl Eq for RequestValidationError

impl Error for RequestValidationError

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.
