Ethereum ABI params.

Variants§

§

Address(H160)

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(U256)

Signed integer.

solidity name: int

§

Uint(U256)

Unsigned 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][]

§

Tuple(Vec<Token>)

Tuple of params of variable types.

solidity name: tuple

Implementations§

source§

impl Token

source

pub fn type_check(&self, param_type: &ParamType) -> bool

Check whether the type of the token matches the given parameter type.

Numeric types (Int and Uint) type check if the size of the token type is of greater or equal size than the provided parameter type.
