Detailed Description

The big-endian 160-bit hash suitable for keeping an Ethereum address.

This type wraps C evmc_address to make sure objects of this type are always initialized.

Constructor & Destructor Documentation

◆ address() [1/2]

constexpr evmc::address::address ( evmc_address  init = {})
inlineconstexprnoexcept

Default and converting constructor.

Initializes bytes to zeros if not other init value provided.

Definition at line 31 of file evmc.hpp.

31{}) noexcept : evmc_address{init} {}
Big-endian 160-bit hash suitable for keeping an Ethereum address.
Definition: evmc.h:69

◆ address() [2/2]

constexpr evmc::address::address ( uint64_t  v)
inlineexplicitconstexprnoexcept

Converting constructor from unsigned integer value.

This constructor assigns the v value to the last 8 bytes [12:19] in big-endian order.

Definition: evmc.hpp:258

◆ operator bytes_view()

constexpr evmc::address::operator bytes_view ( ) const
inlineconstexprnoexcept

Definition at line 64 of file evmc.hpp.

64{ return {bytes, sizeof(bytes)}; }
uint8_t bytes[20]
The 20 bytes of the hash.
