Dynamically-sized types like string, bytes or uint[] are encoded without their length field. The encoding of string or bytes does not apply padding at the end, unless it is part of an array or struct (then it is padded to a multiple of 32 bytes).Encoding the parameters of a function using abi.encode() Solidity has a global variable called abi that has an encode method, so we can use it to encode the parameters of any function.

You can define your own type by creating a struct. They are useful for grouping together related data. Structs can be declared outside of a contract and imported in another contract. Generally, it is used to represent a record.Sorted by: 2. You can split the array by the total byte length of the first struct rounded up to a multiplier of 32 - the slot length - and then decode each chunk separately. In the example below, the length of Struct1Type is just 8 bytes, but the memory and storage slots take up the whole 32byte word. That's why we're splitting at the 32nd index.1.
