You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: config_v2.rs
    path of file: ./repos/blueboat/src/mds
    
    the code of the file until where you have to start completion: use anyhow::Result;
use indexmap::IndexMap;

pub struct MdsConfig {
  pub clusters: IndexMap<String, MdsClusterConfig>,
}

#[derive(Clone)]
pub struct MdsClust
    
  pub fn parse(input: &str) -> Result<Self> {
    let mut clusters: IndexMap<String, MdsClusterConfig> = Default::default();
    for seg in input.split(",") {
      let seg = seg.trim();
      if let Some((name, entry)) = seg.trim().split_once("=") {
        if let Some((path, prefix)) = entry.split_once(":") {
          let entry = MdsClusterConfig {
            path: path.to_string(),
            prefix: prefix.to_string(),
          };
          clusters.insert(name.to_string(), entry);
        } else {
          anyhow::bail!("invalid cluster entry: {}", seg);
        }
      } else {
        anyhow::bail!("invalid cluster config: {}", seg);
      }
    }
    Ok(Self { clusters })
  }
