Enum PositionSideOptional 

#[repr(C)]
pub enum PositionSideOptional {
    NoPositionSide = 0,
    Flat = 1,
    Long = 2,
    Short = 3,
}

The stable zero-inclusive position-side representation required by the existing C ABI.

Use Option<PositionSide> for ordinary Rust optionality.

Variants

NoPositionSide = 0

Compatibility value for no specified position side.

This value may be removed in a future version.

Flat = 1

A neutral/flat position.

Long = 2

A long position.

Short = 3

A short position.
