Implementations

impl<T: UnsignedDecimal> NonZero<T>

pub fn inverse(self) -> Self

Intended for use with cw-storage-plus.

pub fn try_from_signed(src: Signed<T>) -> Result<Self>

Try to convert a signed value into a non-zero.

pub fn checked_add(self, rhs: T) -> Result<Self>

Add an unsigned value to this non-zero

This can fail due to overflow error, but is guaranteed to not give a value of 0.

pub fn checked_sub(self, rhs: T) -> Result<Self>

Subtract an unsigned value.

This can fail if the result would be either negative or zero.

pub fn checked_add_signed(self, rhs: Signed<T>) -> Result<Self>

Try to add a signed value to this, erroring if it results in a negative or zero result.

pub fn checked_sub_signed(self, rhs: Signed<T>) -> Result<Self>

Try to subtract a signed value from this, erroring if it results in a negative or zero result.

pub fn one() -> Self

The value 1.

impl NonZero<Collateral>

pub fn checked_mul_non_zero( self, rhs: NonZero<Decimal256>, ) -> Result<NonZero<Collateral>>

Multiply by the given non-zero decimal.

pub fn checked_div_collateral( self, rhs: NonZero<Collateral>, ) -> Result<NonZero<Decimal256>>

Divide two non-zero collateral values to get the ratio between them.

This can be used for cases like calculating the max gains.
