    // Required methods
    fn long_amount(&self) -> Result<Self::Num>;
    fn short_amount(&self) -> Result<Self::Num>;
}

Balanced amounts.

Required Associated Types

type Num: Num + Unsigned<Signed = Self::Signed>

Unsigned number type.

type Signed

Signed number type.

Required Methods

fn long_amount(&self) -> Result<Self::Num>

Get the long token amount (when this is a token balance), or long usd value (when this is a usd value balance).

fn short_amount(&self) -> Result<Self::Num>

Get the short token amount (when this is a token balance), or short usd value (when this is a usd value balance).
