Struct AllowListReader 

pub struct AllowListReader { /* private fields */ }

Reads the GPv2AllowListAuthentication contract to check solver authorization.

Example

use alloy_primitives::address;
use cow_rs::settlement::reader::AllowListReader;

let allow_list = address!("2c4c28DDBdAc9C5E7055b4C863b72eA0149D8aFE");
let reader = AllowListReader::new("https://rpc.sepolia.org", allow_list);
let is_solver = reader.is_solver(address!("1111111111111111111111111111111111111111")).await?;

Implementations

impl AllowListReader

pub fn new(rpc_url: impl Into<String>, allow_list: Address) -> Self

Create a new allow-list reader.

Arguments

• rpc_url - The JSON-RPC endpoint URL.
• allow_list - The Address of the GPv2AllowListAuthentication contract.

Returns

A new AllowListReader targeting the specified contract.

pub const fn allow_list_address(&self) -> Address

Return the allow-list contract address.

Returns

The allow-list contract Address.

pub async fn is_solver(&self, address: Address) -> Result<bool, CowError>

Check whether an address is an authorized solver.

Calls isSolver(address) on the allow-list contract.

Arguments

• address - The Address to check.

Returns

true if the address is an authorized solver.

Errors

Returns CowError::Rpc on RPC failure or CowError::Parse if the response cannot be decoded.
