Implementations

source

impl<'_> PoolTokenConverter<'_>

source

pub fn token_a_rate(&self, pool_tokens: u64) -> Option<(u64, u64, u64 )>

Computes the amount of token A backing the given amount of pool tokens.

source

pub fn token_b_rate(&self, pool_tokens: u64) -> Option<(u64, u64, u64 )>

Computes the amount of token B backing the given amount of pool tokens.

source

pub fn lp_tokens_for_a_excluding_fees(&self, token_a_amount: u64) -> Option<u64>

Calculates the number of LP tokens that correspond to an amount of token A. This does not take withdraw fees into account.

source

pub fn lp_tokens_for_b_excluding_fees(&self, token_b_amount: u64) -> Option<u64>

Calculates the number of LP tokens that correspond to an amount of token B. This does not take withdraw fees into account.
