Struct Token

pub struct Token {
    pub name: &'static str,
    pub decimals: u8,
}

Name and decimals of a given token.

Fields

name: &'static str

The short name (ticker) of the token

decimals: u8

The number of decimals the token has (smallest granularity of the token)

Implementations

impl Token

pub fn amount(&self, amount: u128) -> TokenAmount

Creates the specified amount of Token with its name and decimals filled from the [TokenRegistry] variant.

let token: Token = TokenRegistry::Dot.into();
let my_amount = token.amount(100_000_000);
assert_eq!(format!("{}", my_amount), "0.010 DOT");
assert_eq!(format!("{:?}", my_amount), "0.010 DOT (100,000,000)");

Trait Implementations

impl Clone for Token

fn clone(&self) -> Token

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Token

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

Formats the value using the given formatter.

impl From<TokenRegistry> for Token

fn from(x: TokenRegistry) -> Self

Converts to this type from the input type.

impl Hash for Token

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

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 Ord for Token

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Token

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for Token

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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