pub trait AbiEncodeTrait

Trait functions

encode

Encodes felt252 values into EVM calldata for the specified types.

This function is the primary entry point for encoding values into EVM-compatible calldata in Starknet Cairo. It accepts a list of EVM-compatible types and a corresponding list of felt252 values, then encodes them according to EVM ABI encoding standards.

This function is typically implemented as a dispatcher that calls appropriate encoding routines (e.g., encode_uint, encode_tuple, encode_array, etc.) based on the types passed in.

Arguments

  • self - Reference to EVMCalldata context which maintains the calldata byte array, current offset, dynamic data section and dynamic offset.
  • types - A list (Span) of EVMTypes to encode.
  • values - A list (Span) of felt252 values to encode according to the types.

Returns

  • ByteArray - The encoded EVM calldata as a byte array.

Usage

This function is typically called when preparing calldata for EVM contract calls from within Cairo smart contracts.
