Expand description
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 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(())
}
