Function deserialize_rpc_urls

pub fn deserialize_rpc_urls<'de, D>(
    deserializer: D,
) -> Result<Option<Vec<RpcConfig>>, D::Error>
where
    D: Deserializer<'de>,

Custom deserializer for Option<Vec<RpcConfig>> that supports multiple input formats.

This function is designed to be used with #[serde(deserialize_with = "...")] and supports:

• Simple format: Array of strings, e.g., ["https://rpc1.com", "https://rpc2.com"] Each string is converted to an RpcConfig with default weight (100).

• Extended format: Array of objects, e.g., [{"url": "https://rpc.com", "weight": 50}] Each object is deserialized directly as an RpcConfig.

• Mixed format: Array containing both strings and objects e.g., ["https://rpc1.com", {"url": "https://rpc2.com", "weight": 50}]

Example Usage

use serde::Deserialize;
use openzeppelin_relayer::models::relayer::{RpcConfig, deserialize_rpc_urls};

#[derive(Deserialize)]
struct MyConfig {
    #[serde(default, deserialize_with = "deserialize_rpc_urls")]
    rpc_urls: Option<Vec<RpcConfig>>,
}
