An implementation of eval() for Rust.
The main struct in this crate is EvalContext. You create one, then ask it
to eval bits of code. Any defined functions, variables etc are local to that
context.
rust
let mut context = EvalContext::new();
context.eval("let s = String::new();")?;
context.eval(r#"s.push_str("Hello ");"#)?;
context.eval(r#"s.push_str("World");"#)?;
context.eval(r#"println!("{}", s);"#)?;
You must call evcxr::runtime_hook() at the top of main, otherwise the
library becomes a fork-bomb.
I'll not go into too much detail here, since the purpose of this library is really to provide functionality to evcxr_jupyter and evcxr_repl. If you'd like to try using this crate for something else, drop me an email, or file an issue on the repository and we can figure out your use case.
See .github/workflows/ci.yml for the current minimum supported rust version. Generally rare that we support much older versions than the latest stable, since - mostly because our upstream dependencies make use of new rust features pretty quickly after they stabalize.
