Struct mlua::prelude::LuaString [−][src]
pub struct LuaString<'lua>(_);
Handle to an internal Lua string.
Unlike Rust strings, Lua strings may not be valid UTF-8.
Implementations
impl<'lua> String<'lua>
[src]
impl<'lua> String<'lua>
[src]pub fn to_str(&self) -> Result<&str>
[src]
Get a &str
slice if the Lua string is valid UTF-8.
Examples
let globals = lua.globals(); let version: String = globals.get("_VERSION")?; assert!(version.to_str()?.contains("Lua")); let non_utf8: String = lua.load(r#" "test\255" "#).eval()?; assert!(non_utf8.to_str().is_err());
pub fn as_bytes(&self) -> &[u8]ⓘ
[src]
Get the bytes that make up this string.
The returned slice will not contain the terminating nul byte, but will contain any nul bytes embedded into the Lua string.
Examples
let non_utf8: String = lua.load(r#" "test\255" "#).eval()?; assert!(non_utf8.to_str().is_err()); // oh no :( assert_eq!(non_utf8.as_bytes(), &b"test\xff"[..]);
pub fn as_bytes_with_nul(&self) -> &[u8]ⓘ
[src]
Get the bytes that make up this string, including the trailing nul byte.
