Struct prevrandao_1Call

pub struct prevrandao_1Call {
    pub newPrevrandao: U256,
}

Sets block.prevrandao. Not available on EVM versions before Paris. Use difficulty instead. If used on unsupported EVM versions it will revert. Function with signature prevrandao(uint256) and selector 0x9cb1c0d4.

function prevrandao(uint256 newPrevrandao) external;

Fields

newPrevrandao: U256

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
