ethabi-decode
This library is a codec for ABI-encoded data and event logs. It is a fork of ethabi with a focus on providing decode functionality in environments where libstd
may not be available.
For compatibility with constrained no_std
environments, the design of this library differs from the the upstream ethabi in several respects, including:
- ABI's need to be specified as code rather than being loaded from JSON (No SERDE support).
- Use of
Vec<u8>
instead ofstd::string::String
for owned strings. - Anything to do with human-readable error and display output was excised.

Example
Decode an event log:
use ethabi_decode::{Event, ParamKind, Token};
fn decode_event_log(topics: Vec<H256>, data: Vec<u8>) -> Vec<Token> {
let event = Event {
signature: "SomeEvent(address,int256)",
inputs: vec![
Param { kind: ParamKind::Address, indexed: true },
Param { kind: ParamKind::Int(256), indexed: false },
],
anonymous: false,
};
event.decode(topics, data).unwrap()
}
