Struct PoolState

Source 
pub struct PoolState {
    pub lefts: u128,
    pub rights: u128,
    pub price_accum: u128,
    pub liqs: u128,
}
Expand description

The internal status of a Melswap pool. Notably, this does not identify which pool this is, or even what tokens are the “lefts” and “rights”.

Fields§

§lefts: u128

How many “left-hand” tokens (the token with the lexicographically smaller Denom) are there in the pool, in microunits.

§rights: u128

How many “right-hand” tokens are there in the pool.

§price_accum: u128

A Uniswap-like TWAP of the price. TODO document this more

§liqs: u128

How many liquidity tokens have been issued

Implementations§

Source§

impl PoolState
