Struct eosio::Asset

pub struct Asset {
    pub amount: i64,
    pub symbol: Symbol,
}

Stores information for owner of asset https://github.com/EOSIO/eosio.cdt/blob/4985359a30da1f883418b7133593f835927b8046/libraries/eosiolib/core/eosio/asset.hpp#L18-L369

Fields

amount: i64

The amount of the asset

symbol: Symbol

The symbol name of the asset

Methods

impl Asset

pub fn zero<T: Into<Symbol>>(symbol: T) -> Self

#[must_use] pub fn is_valid(&self) -> bool
