Struct CallDecoder 

pub struct CallDecoder { /* private fields */ }

Decode input data parsing input data.

Implementations

impl CallDecoder

pub fn from_signatures<S: AsRef<str>>(signatures: &[S]) -> Result<Self>

Initialize decoder from event signatures.

use hypersync_client::CallDecoder;
let decoder = CallDecoder::from_signatures(&[
   "transfer(address to,uint256 amount)",
]).unwrap();

pub fn decode_input(&self, data: &Data) -> Result<Option<Vec<DynSolValue>>>

Parse input data and return result

Returns Ok(None) if signature not found.

pub fn decode_output( &self, data: &Data, function_signature: &str, ) -> Result<Option<Vec<DynSolValue>>>

Parse output data and return result

Decodes the output field from a trace and returns the decoded values in a Vec<DynSolValue>. If the function signature is not found or the decoding fails, it returns Ok(None) as the result to match the behavior of decode_input
