Struct Function

pub struct Function { /* private fields */ }

A set of arguments we can provide to a transaction, containing the function name, arguments, the amount of gas to use and deposit.

Implementations

impl Function

pub fn new(name: &str) -> Self

Initialize a new instance of Function, tied to a specific function on a contract that lives directly on a contract we’ve specified in Transaction.

pub fn args(self, args: Vec<u8>) -> Self

Provide the arguments for the call. These args are serialized bytes from either a JSON or Borsh serializable set of arguments. To use the more specific versions with better quality of life, use args_json or args_borsh.

pub fn args_json<U: Serialize>(self, args: U) -> Self

Similar to args, specify an argument that is JSON serializable and can be accepted by the equivalent contract. Recommend to use something like serde_json::json! macro to easily serialize the arguments.

pub fn args_borsh<U: BorshSerialize>(self, args: U) -> Self

Similar to args, specify an argument that is borsh serializable and can be accepted by the equivalent contract.

pub fn deposit(self, deposit: NearToken) -> Self

Specify the amount of tokens to be deposited where deposit is the amount of tokens in yocto near.

pub fn gas(self, gas: NearGas) -> Self

Specify the amount of gas to be used.

pub fn max_gas(self) -> Self

Use the maximum amount of gas possible to perform this function call into the contract.

Trait Implementations

impl Debug for Function

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

Formats the value using the given formatter.
