Variants

Address([u8; 20])

Address.

solidity name: address Encoded to left padded [0u8; 32].

FixedBytes(Vec<u8>)

Vector of bytes with known size.

solidity name eg.: bytes8, bytes32, bytes64, bytes1024 Encoded to right padded [0u8; ((N + 31) / 32) * 32].

Bytes(Vec<u8>)

Vector of bytes of unknown size.

solidity name: bytes Encoded in two parts. Init part: offset of 'closing part`. Closing part: encoded length followed by encoded right padded bytes.

Int([u8; 32])

Signed integer.

solidity name: int

Uint([u8; 32])

Unisnged integer.

solidity name: uint

Bool(bool)

Boolean value.

solidity name: bool Encoded as left padded [0u8; 32], where last bit represents boolean value.

String(String)

String.

solidity name: string Encoded in the same way as bytes. Must be utf8 compliant.

FixedArray(Vec<Token>)

Array with known size.

solidity name eg.: int[3], bool[3], address[][8] Encoding of array is equal to encoding of consecutive elements of array.

Array(Vec<Token>)

Array of params with unknown size.

solidity name eg. int[], bool[], address[5][]
