Trait Pool 

pub trait Pool: Balance + Sized {
    // Required method
    fn checked_apply_delta(&self, delta: Delta<&Self::Signed>) -> Result<Self>;

    // Provided methods
    fn apply_delta_to_long_amount(&mut self, delta: &Self::Signed) -> Result<()> { ... }
    fn apply_delta_to_short_amount(
        &mut self,
        delta: &Self::Signed,
    ) -> Result<()> { ... }
    fn checked_cancel_amounts(&self) -> Result<Self>
       where Self::Signed: CheckedSub { ... }
}

A balance for holding tokens, usd values, or factors

Required Methods

fn checked_apply_delta(&self, delta: Delta<&Self::Signed>) -> Result<Self>

Checked apply delta amounts.

Provided Methods

fn apply_delta_to_long_amount(&mut self, delta: &Self::Signed) -> Result<()>

Apply delta to long amount.

fn apply_delta_to_short_amount(&mut self, delta: &Self::Signed) -> Result<()>

Apply delta to short amount.

fn checked_cancel_amounts(&self) -> Result<Self>

where Self::Signed: CheckedSub,

Cancel the amounts, for example, (1000, 200) -> (800, 0).

Warning

• Note that the default implementation may lead to unnecessary failures due to the numeric range limitations of signed integers.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
