Struct rlua::LuaString

pub struct LuaString<'lua>(_);

Handle to an internal Lua string.

Unlike Rust strings, Lua strings may not be valid UTF-8.

Methods

impl<'lua> LuaString<'lua>

fn to_str(&self) -> LuaResult<&str>

Get a &str slice if the Lua string is valid UTF-8.

Example

let lua = Lua::new();
let globals = lua.globals();

let version: LuaString = globals.get("_VERSION").unwrap();
assert!(version.to_str().unwrap().contains("Lua"));

let non_utf8: LuaString = lua.eval(r#"  "test\xff"  "#).unwrap();
assert!(non_utf8.to_str().is_err());
