Implementations

impl Parameter

pub fn new_int(bytes: [u8; 32], signed: bool) -> Self

pub fn new_fixed_bytes(bytes: &[u8]) -> Self

Creates a new FixedBytes parameter.

pub fn new_bytes(bytes: &[u8]) -> Self

Creates a new Bytes parameter.

impl Parameter

pub fn static_encode(&self) -> Vec<u8>

Encodes strictly the data part of the underlying type.

It will not check whether the parameter is dynamic or not, it simply encodes the enclosed data in place. For some types, it first writes the number of elements of the data in bytes. For further info, check the Solidity contract ABI specification.

pub fn is_dynamic(&self) -> bool

Recursively checks wether a given parameter is dynamic.

For example, a Tuple can be dynamic if any of its contained types are dynamic. Additionally, a FixedArray is static if it contains values with static type and dynamic otherwise.

pub fn decode(parameter_type: &ParameterType, raw_bytes: &[u8]) -> (Self, usize)
