Implementations§

Source§

impl<E, Args, R, Abi> CallParams<E, Call, Args, R, Abi>
where E: Environment,

Source

pub fn callee(&self) -> &H160

Returns the contract address of the called contract instance.

Returns the chosen ref time limit for the called contract execution.

Source

pub fn proof_size_limit(&self) -> u64

Returns the chosen proof size limit for the called contract execution.

Source

pub fn storage_deposit_limit(&self) -> Option<U256>

pub fn invoke(&self) -> R

Invokes the contract with the given built-up call parameters.

§Panics

This method panics if it encounters an ink::env::Error or an [ink::primitives::LangError][ink_primitives::LangError]. If you want to handle those use the try_invoke method instead.
