Struct Token 

pub struct Token {
    pub chain: SharedChain,
    pub address: Address,
    pub name: String,
    pub symbol: String,
    pub decimals: u8,
}

Represents a cryptocurrency token on a blockchain network.

Fields

chain: SharedChain

The blockchain network where this token exists.

address: Address

The blockchain address of the token contract.

name: String

The full name of the token.

symbol: String

The token’s ticker symbol.

decimals: u8

The number of decimal places used to represent fractional token amounts.

Implementations

impl Token

pub fn new( chain: SharedChain, address: Address, name: String, symbol: String, decimals: u8, ) -> Self

Creates a new Token instance with the specified properties.

pub fn is_stablecoin(&self) -> bool

Returns true if this token is a stablecoin.

Checks against common stablecoin symbols including USD-pegged tokens, Euro-pegged tokens, and other algorithmic/collateralized stablecoins.

pub fn is_native_currency(&self) -> bool

Returns true if this token is a native blockchain currency wrapper.

Identifies wrapped versions of native currencies like WETH (Wrapped ETH), WMATIC (Wrapped MATIC), WBNB (Wrapped BNB), etc.

pub fn get_token_priority(&self) -> u8

Returns the priority of this token for base/quote determination.

Lower numbers indicate higher priority to become the quote token (pricing currency). This follows market conventions where trades are quoted in the most liquid/stable assets.

Priority Levels

• 1: Stablecoins (USDC, USDT, DAI, etc.) - Highest priority to be quote
• 2: Native currencies (WETH, WMATIC, WBNB, etc.) - Medium priority
• 3: Other tokens - Lowest priority (typically become base tokens)

Trait Implementations

impl Clone for Token

fn clone(&self) -> Token

Returns a duplicate 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<'de> Deserialize<'de> for Token

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Token

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

Formats the value using the given formatter.

impl<'py> IntoPyObject<'py> for Token

type Target = Token

The Python output type

type Output = Bound<'py, <Token as IntoPyObject<'py>>::Target>

The smart pointer type to use.

type Error = PyErr

The type returned in the event of a conversion error.

fn into_pyobject( self, py: Python<'py>, ) -> Result<<Self as IntoPyObject<'_>>::Output, <Self as IntoPyObject<'_>>::Error>

Performs the conversion.

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 PyClass for Token

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for Token

const IS_BASETYPE: bool = false

#[pyclass(subclass)]

const IS_SUBCLASS: bool = false

#[pyclass(extends=…)]

const IS_MAPPING: bool = false

#[pyclass(mapping)]

const IS_SEQUENCE: bool = false

#[pyclass(sequence)]

const IS_IMMUTABLE_TYPE: bool = false

#[pyclass(immutable_type)]

const RAW_DOC: &'static CStr = /// Represents a cryptocurrency token on a blockchain network.

Docstring for the class provided on the struct or enum.

const DOC: &'static CStr

Fully rendered class doc, including the text_signature if a constructor is defined.

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<Token>

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.
