Constructor & Destructor Documentation

bytes32() [1/2]

constexpr evmc::bytes32::bytes32 ( evmc_bytes32  init = {} )

inlineconstexprnoexcept

Default and converting constructor.

Initializes bytes to zeros if not other init value provided.

Definition at line 75 of file evmc.hpp.

{}) noexcept : evmc_bytes32{init} {}

bytes32() [2/2]

constexpr evmc::bytes32::bytes32 ( uint64_t  v )

inlineexplicitconstexprnoexcept

Converting constructor from unsigned integer value.

This constructor assigns the v value to the last 8 bytes [24:31] in big-endian order.

Definition at line 81 of file evmc.hpp.
