}

Raw AMM state for a single pool. Slot i corresponds to PoolBooks.metas[i].

Strategies use this to compute swap output from the pricing function directly rather than relying on pre-computed synthetic L2Books.

• V2 pools: use reserve0(), reserve1(), fee_ppm
• V3/CLMM pools: use sqrt_price_x64, tick, liquidity, fee_ppm, tick_spacing

Fields

reserve0_lo: u64

Lower 64 bits of reserve0.

reserve0_hi: u64

Upper 64 bits of reserve0 (usually 0 for practical pools).

reserve1_lo: u64

Lower 64 bits of reserve1.

reserve1_hi: u64

Upper 64 bits of reserve1.

sqrt_price_x64: u128

sqrt(price) in Q64.64 fixed-point (converted from Q64.96 by CC). To get price: (sqrt_price_x64 as f64 / 2^64)^2.

liquidity: u128

Active liquidity at the current tick.

tick: i32

Current tick index. Price at tick t ≈ 1.0001^t.

tick_spacing: i32

Tick spacing (V3 only: 1, 10, 60, 200).

fee_ppm: u32

Swap fee in parts-per-million (3000 = 0.3%).

pool_type: u8

Pool type: 0=V2, 1=V3/CLMM, 2=stableswap.

_pad0: [u8; 3]

last_block: u64

Block/slot number when this state was observed.

last_update_ns: u64

Nanosecond timestamp of last update.

Implementations

impl PoolAmm

pub fn reserve0(&self) -> u128

Reconstruct reserve0 as u128.

pub fn reserve1(&self) -> u128

Reconstruct reserve1 as u128.

pub fn is_v2(&self) -> bool

Whether this is a V2 (constant-product) pool.

pub fn is_v3(&self) -> bool

Whether this is a V3/CLMM (concentrated liquidity) pool.

pub fn is_valid(&self) -> bool

Whether this state has been populated (non-zero block).

pub fn fee_bps(&self) -> u32

Fee as basis points (e.g. 3000 ppm → 30 bps).
