Enum PoolKind 

#[non_exhaustive]
pub enum PoolKind {
    V2,
    V3,
    V4,
}

Discriminant for the three pool-table families.

V2 corresponds to UniswapV2PoolTableBase (Uniswap V2 and V2-style forks); V3 corresponds to UniswapV3PoolTableBase (Uniswap V3 and V3-style forks); V4 corresponds to UniswapV4PoolTable.

All V2/V3 subtypes share the pools database table (single ID sequence), so a pool_id is unique within V2 and within V3 — no collision between the two. V4 pools use a separate managed_pools table, so the PoolKind discriminant disambiguates V4 IDs from V2/V3 IDs.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
