Crate warp_api_ffi

Expand description

A library for fast synchronization of y/zcash blockchain

Implements the warp sync algorithm for sapling
Multi Account management

Example

use warp_api_ffi::api::account::{get_backup, new_account};
use warp_api_ffi::api::sync::coin_sync;
use warp_api_ffi::{CoinConfig, init_coin, set_coin_lwd_url};

use std::sync::Mutex;

lazy_static! {
    static ref CANCEL: Mutex<bool> = Mutex::new(false);
}
