Substreams
for AntelopeThis library contains the generated protobuffer for the Antelope blocks as well as helper methods to extract and parse block data.

Or, using actions()
filter to filter all actions of Statelog
type from myaccount
account:
src/lib.rs
#[substreams::handlers::map]
fn map_actions(param_account: String, block: substreams_antelope::Block) -> Result<Actions, substreams::errors::Error> {
Ok(Actions {
statelogs: block.actions::<abi::contract::actions::Statelog>(&["myaccount"])
.map(|(action, trx)| StateLog {
// set action fields
})
.collect(),
})
}
To generate ABI bindings for your smart contract you can add abi/contract.abi.json
file containing the smart contract ABI, as well as the following build.rs
file to the root of your project. This will ensure that src/abi/contract.rs
module containing Rust bindings for your smart contract is always generated in your project:
build.rs
fn main() {
substreams_antelope::Abigen::new("Contract", "abi/gems.blend.abi.json")
.expect("failed to load abi")
.generate()
.expect("failed to generate contract")
.write_to_file("src/abi/gems.blend.abi.rs")
.expect("failed to write contract");
}
