Struct Builder 

pub struct Builder<T: Transport> { /* private fields */ }

A configuration builder for contract deployment.

Implementations

impl<T: Transport> Builder<T>

pub fn confirmations(self, confirmations: usize) -> Self

Number of confirmations required after code deployment.

pub fn options(self, options: Options) -> Self

Deployment transaction options.

pub fn poll_interval(self, interval: Duration) -> Self

Confirmations poll interval.

pub async fn execute<P, V>( self, code: V, params: P, from: Address, ) -> Result<Contract<T>, Error>

where P: Tokenize, V: AsRef<str>,

Execute deployment passing code and contructor parameters.

pub async fn sign_and_execute<P, V>( self, code: V, params: P, from: Address, password: &str, ) -> Result<Contract<T>, Error>

where P: Tokenize, V: AsRef<str>,

Execute deployment passing code and constructor parameters.

Unlike the above execute, this method uses sign_raw_transaction_with_confirmation instead of sign_transaction_with_confirmation, which requires the account from which the transaction is sent to be unlocked.

pub async fn sign_with_key_and_execute<P, V, K>( self, code: V, params: P, from: K, chain_id: Option<u64>, ) -> Result<Contract<T>, Error>

where P: Tokenize, V: AsRef<str>, K: Key,

Execute deployment passing code and constructor parameters.

Unlike the above sign_and_execute, this method allows the caller to pass in a private key to sign the transaction with and therefore allows deploying from an account that the ethereum node doesn’t need to know the private key for.

An optional chain_id parameter can be passed to provide replay protection for transaction signatures. Passing None would create a transaction WITHOUT replay protection and should be avoided. You can obtain chain_id of the network you are connected to using web3.eth().chain_id() method.
