Struct TokenState 

pub struct TokenState {
    pub balance: U256,
    pub allowance: U256,
}

Token state containing balance and allowance information.

Returned by batch_token_state to provide a structured view of an account’s token state.

Fields

balance: U256

The token balance of the owner

allowance: U256

The allowance granted to the spender

Implementations

impl TokenState

pub fn can_transfer(&self, amount: U256) -> bool

Check if the owner can transfer the specified amount.

Returns true if balance >= amount AND allowance >= amount.

pub fn needs_approval(&self, amount: U256) -> bool

Check if approval is needed for the specified amount.

Returns true if allowance < amount.

pub fn has_sufficient_balance(&self, amount: U256) -> bool

Check if the owner has sufficient balance.

Trait Implementations

impl Clone for TokenState

fn clone(&self) -> TokenState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TokenState

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

Formats the value using the given formatter.

impl PartialEq for TokenState

fn eq(&self, other: &TokenState) -> 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.
