Function diff_roots 

pub fn diff_roots(
    base_slot: u64,
    target_slot: u64,
    buffer: &[[u8; 32]],
) -> RootsDiff

Computes the sequence of newly written roots between two slots.

The returned delta contains every root written during the half-open slot range [base_slot, target_slot).

The input buffer is treated as a circular buffer, with its length defining the modulo capacity.

Arguments

• base_slot - First slot represented by the delta.
• target_slot - Slot immediately following the final recorded root.
• buffer - Circular root buffer.

Complexity

O(target_slot - base_slot)
