我正在使用Rust和crate ethers通过从EVM链阅读日志，我正在处理事务散列和地址，它们被表示为U256或H160对象，请考虑下面的示例代码：

use ethers::prelude::{Log};
use ethers::types::{Address, H160, H256, U256};

async fn print_log_details(&self, log: &Log) {
    let block_number = log.block_number.unwrap();
    let from: H160 = Address::from(log.topics[1]);
    let to: H160 = Address::from(log.topics[2]);
    let token_id: U256 = U256::decode(log.topics[3]).unwrap();
    let transaction_hash: H256 = log.transaction_hash.unwrap();

    dbg!(log.clone());
    println!(
        "block_number = {}, from = {}, to = {}, tokenId = {}, transactionHash = {}",
        block_number, from, to, token_id, transaction_hash
    );
}

产生如下输出：

[src/main.rs:54] log.clone() = Log {
address: 0x7ea3cca10668b8346aec0bf1844a49e995527c8b,

block_number = 13032069, from = 0x6035…df49, to = 0x4a6e…e5ec, tokenId = 3061, transactionHash = 0xa520…bddf

我想在println中看到完整的十六进制形式的from，to和transaction，而不是截断的形式。我该怎么做呢？看起来这些结构体上的Display特性截断了输出。
