type.Result

Type Definition tauri::​Result

type Result<T, E = Error> = Result<T, E>;

Alias for a Result with error type anyhow::Error. Result<T, Error>

This is a reasonable return type to use throughout your application but also for fn main; if you do, failures will be printed along with any [context][Context] and a backtrace if one was captured.

anyhow::Result may be used with one or two type parameters.

use anyhow::Result;

fn demo1() -> Result<T> {...}
           // ^ equivalent to std::result::Result<T, anyhow::Error>

fn demo2() -> Result<T, OtherError> {...}
           // ^ equivalent to std::result::Result<T, OtherError>

Example

use anyhow::Result;

fn main() -> Result<()> {
    let config = std::fs::read_to_string("cluster.json")?;
    let map: ClusterMap = serde_json::from_str(&config)?;
    println!("cluster info: {:#?}", map);
    Ok(())
}
