Enum ContractConfigError 

#[non_exhaustive]
pub enum ContractConfigError {
    MissingOptionRight,
    UnrecognizedOptionRight {
        right: String,
    },
    MissingStrike,
    MissingLastTradeDate,
    UnrecognizedSecurityType {
        security_type: String,
    },
}

Reasons a ContractConfig cannot be mapped to a valid Contract.

Every variant represents an input that would otherwise force the builder to silently fabricate a wrong contract (e.g. defaulting a missing option right to Call, or an unknown security_type to a stock). Surfacing these at construction — rather than deferring to an opaque IBKR submission rejection — keeps failures observable, per the library’s contract.

#[non_exhaustive]: new validation reasons may be added without a breaking change as the contract builders grow.

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.

MissingOptionRight

An OPT contract was configured without a right.

UnrecognizedOptionRight

A right was supplied but is not one of C/CALL/P/PUT.

Fields

right: String

MissingStrike

An OPT contract was configured without a strike.

MissingLastTradeDate

A FUT or OPT contract was configured without a last_trade_date.

UnrecognizedSecurityType

The security_type is not one of the supported STK/FUT/OPT/CASH.

Fields

security_type: String

Trait Implementations

impl Clone for ContractConfigError

fn clone(&self) -> ContractConfigError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ContractConfigError

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

Formats the value using the given formatter.

impl Display for ContractConfigError

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

Formats the value using the given formatter.

impl Eq for ContractConfigError

impl Error for ContractConfigError

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 PartialEq for ContractConfigError

fn eq(&self, other: &ContractConfigError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
