This crate provides a macro that enables the familiar try-catch syntax of other programming languages.
It can be used to easlily group errors and manage them dynamically by type rather than value.
rust
use std::*;
use serde_json::Value;
catch! {
try {
let data = fs::read_to_string("data.json")?;
let json: Value = serde_json::from_str(&data)?;
}
catch error: io::Error {
println!("Failed to open the file: {}", error)
}
catch json_err: serde_json::Error {
println!("Failed to serialize data: {}", json_err)
}
}
