描述

The GraphQL server coverts bytes into the hex string to return it to the user. During this convert process, we take vector by value.

We have many cases where we clone vectors instead of passing it as a reference.

This issue is created to replace Vec<u8> with Cow<[u8]> or Cow<Vec<u8>> and allow usage of references.

研究方向
The issue involves replacing `Vec<u8>` with `Cow<[u8]>` or `Cow<Vec<u8>>` in the hex string conversion within the GraphQL server. Start by searching for functions that take `Vec<u8>` by value and call `clone()` on it. Examine the conversion logic in the GraphQL server code, likely in files related to hex encoding. Check the existing comments and PRs for any prior discussions or approaches.
