Enum ContingencyTypeOptional 

#[repr(C)]
pub enum ContingencyTypeOptional {
    NoContingency = 0,
    Oco = 1,
    Oto = 2,
    Ouo = 3,
}

The stable zero-inclusive contingency-type representation required by the existing C ABI.

Use Option<ContingencyType> for ordinary Rust optionality.

Variants

NoContingency = 0

Compatibility value for no specified contingency type.

This value may be removed in a future version.

Oco = 1

One-Cancels-the-Other.

Oto = 2

One-Triggers-the-Other.

Ouo = 3

One-Updates-the-Other.
