Trait Implementations

impl Add<Amount> for Amount

type Output = Amount

The resulting type after applying the + operator.

fn add(self, other: Amount) -> <Amount as Add<Amount>>::Output

Performs the + operation.

impl AddAssign<Amount> for Amount

fn add_assign(&mut self, other: Amount)

Performs the += operation.

impl Clone for Amount

fn clone(&self) -> Amount

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Amount

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Deserial for Amount

fn deserial<R>(source: &mut R) -> Result<Amount, ParseError>where R: Read,

Attempt to read a structure from a given source, failing if an error occurs during deserialization or reading.

impl FromStr for Amount

Parse from string in CCD units. The input string must be of the form n[.m] where n and m are both digits. The notation [.m] indicates that that part is optional.

• if n starts with 0 then it must be 0l
• m can have at most 6 digits, and must have at least 1
• both n and m must be non-negative.

type Err = AmountParseError

The associated error which can be returned from parsing.

fn from_str(v: &str) -> Result<Amount, <Amount as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for Amount

fn hash<__H>(&self, state: &mut __H)where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Mul<Amount> for u64

type Output = Amount

The resulting type after applying the * operator.

fn mul(self, other: Amount) -> <u64 as Mul<Amount>>::Output

Performs the * operation.

impl Mul<u64> for Amount

type Output = Amount

The resulting type after applying the * operator.

fn mul(self, other: u64) -> <Amount as Mul<u64>>::Output

Performs the * operation.

impl MulAssign<u64> for Amount

fn mul_assign(&mut self, other: u64)

impl Ord for Amount

fn cmp(&self, other: &Amount) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

impl PartialEq<Amount> for Amount

fn eq(&self, other: &Amount) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn partial_cmp(&self, other: &Amount) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
