Enum ContinuousFutureAdjustmentType 

#[repr(C)]
pub enum ContinuousFutureAdjustmentType {
    BackwardSpread = 1,
    ForwardSpread = 2,
    BackwardRatio = 3,
    ForwardRatio = 4,
}

The price-adjustment scheme applied when stitching segment contracts into a continuous future series.

The direction (backward vs. forward) selects the anchor contract:

• Backward modes anchor on the most recent contract; prices in older segments are shifted into the latest contract’s frame.
• Forward modes anchor on the first contract; prices in later segments are shifted into the first contract’s frame.

The kind (spread vs. ratio) selects how each transition’s offset is combined:

• Spread modes accumulate additive offsets (post_price - pre_price).
• Ratio modes accumulate multiplicative factors (post_price / pre_price) and require strictly positive prices.

Variants

BackwardSpread = 1

Additive adjustment, anchored on the most recent contract.

ForwardSpread = 2

Additive adjustment, anchored on the first contract.

BackwardRatio = 3

Multiplicative adjustment, anchored on the most recent contract.

ForwardRatio = 4

Multiplicative adjustment, anchored on the first contract.
