Trait ExtWithInfo

pub trait ExtWithInfo: PrecompileExt {
    // Required method
    fn instantiate(
        &mut self,
        limits: &CallResources<Self::T>,
        code: Code,
        value: U256,
        input_data: Vec<u8>,
        salt: Option<&[u8; 32]>,
    ) -> Result<H160, ExecError>;
}

Environment functions which are available to pre-compiles with HAS_CONTRACT_INFO = true.

Required Methods

fn instantiate( &mut self, limits: &CallResources<Self::T>, code: Code, value: U256, input_data: Vec<u8>, salt: Option<&[u8; 32]>, ) -> Result<H160, ExecError>

Instantiate a contract from the given code.

Returns the original code size of the called contract. The newly created account will be associated with code. value specifies the amount of value transferred from the caller to the newly created account.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
