  • Channel: An asynchronous queue, order by the order in which the elements are pushed
  • HChannel: An asynchronous queue, order by customizable heap
  • PChannel: An asynchronous queue, order by element index(grow from 0) and index must be continuous
• Compress: Provide some functions for compressing and decompressing data
• FunctionalMap and FunctionalSet: Key customizable map and set

INSTALL

npm install @gxchain2/utils

USAGE

const channel = new Channel<string>();
channel.push('123');
channel.push('456');
setTimeout(() => {
  channel.push('789');
}, 1000);
setTimeout(() => {
  channel.push('101112');
}, 2000);
setTimeout(() => {
  channel.abort();
}, 3000);

(async () => {
  for await (const data of channel.generator()) {
    console.log('data:', data);
  }
  console.log('channel end');
})();

const bufferMap = new FunctionalMap<Buffer, string>((a: Buffer, b: Buffer) => a.compare(b));
bufferMap.set(Buffer.from('aaaaaa', 'hex'), 'aaaaaa');
console.log(bufferMap.get(Buffer.from('aaaaaa', 'hex')) === 'aaaaaa'); // true
