API: Get solana leader's IP and TPU port list for next N secs.
Budget: $30 – $250 CAD
Code need to be wrote in Rust.
The API takes a slot number(current_slot) and seconds(window_n) as input and calculates who will be leader in next window_n secs, return the list of validator IP/Port as output. The return list/Vec should be sorted in time ascend way and same validator should be merged into one entry(for example if there's 8 slots for one validator in next window_n secs, should return only one entry for that validator).
The API should get leader schedule and cluster nodes from RPC ONCE per epoch.
The API is defined as
struct LeaderInfo {
validator: String,
ip: String,
tpu_port: u16,
slot: u64, //the earliest slot for this validator.
}
fn get_leaders(current_slot: u64, window_n: u16) -> Result<Vec<LeaderInfo>, Error>
