let config = std::fs::read_to_string("cluster.json")?;
let map: ClusterMap = serde_json::from_str(&config)?;
Ok(map)
}
Example 2 of 5
use anyhow::{Context, Result};
fn main() -> Result<()> {
...
it.detach().context("Failed to detach the important thing")?;
let content = std::fs::read(path)
.with_context(|| format!("Failed to read instrs from {}", path))?;

}
Example 3 of 5
// If the error was caused by redaction, then return a
// tombstone instead of the content.
