}Expand description
A Rust/ink! equivalent of a Solidity ABI type that implements logic for Solidity ABI encoding.
§Rust/ink! to Solidity ABI type mapping
| Rust/ink! type | Solidity ABI type | Notes |
|---|---|---|
bool | bool | |
iN for N ∈ {8,16,32,64,128} | intN | e.g i8 ↔ int8 |
uN for N ∈ {8,16,32,64,128} | uintN | e.g u8 ↔ uint8 |
U256 | uint256 | |
String | string | |
Box<str> | string | |
Address / H160 | address | Address is a type alias for the H160 type used for addresses in pallet-revive |
[T; N] for const N: usize | T[N] | e.g. [i8; 64] ↔ int8[64] |
Vec<T> | T[] | e.g. Vec<i8> ↔ int8[] |
Box<[T]> | T[] | e.g. Box<[i8]> ↔ int8[] |
SolBytes<u8> | bytes1 | |
SolBytes<[u8; N]> for 1 <= N <= 32 | bytesN | e.g. SolBytes<[u8; 32]> ↔ bytes32 |
SolBytes<Vec<u8>> | bytes | |
SolBytes<Box<[u8]>> | bytes | |
(T1, T2, T3, ... T12) | (U1, U2, U3, ... U12) | where T1 ↔ U1, … T12 ↔ U12 e.g. (bool, u8, Address) ↔ (bool, uint8, address) |
&str, &mut str | string | |
&T, &mut T, Box<T> | T | e.g. &i8 ↔ int8 |
&[T], &mut [T] | T[] | e.g. &[i8] ↔ int8[] |
