Module utils

Helper utilities around pre-compiles.

This file contains a number of functions for Solidity type encoding and decoding. Notably these implementations don’t require an allocator, which is why they are here in the first place (e.g. alloy-core requires an allocator for the Solidity bytes type).

Functions

decode_bytes

Simple decoder for a Solidity bytes type.

encode_bool

Encodes a bool to big-endian [u8; 32] with padded zeros.

encode_bytes

Encodes the bytes argument for the Solidity ABI. The result is written to out.

encode_u32

Encodes a u32 to big-endian [u8; 32] with padded zeros.

solidity_selector

Returns the Solidity selector for fn_sig.
