Struct hlua::LuaCode

pub struct LuaCode<'a>(pub &'a str);

Wrapper around a &str. When pushed, the content will be parsed as Lua code and turned into a function.

Since pushing this value can fail in case of a parsing error, you must use the checked_set method instead of set.

Note: This struct is a wrapper around LuaCodeFromReader. There’s no advantage in using it except that it is more convenient. More advanced usages (such as returning a Lua function from a Rust function) can be done with LuaCodeFromReader.

Example

let mut lua = hlua::Lua::new();
lua.checked_set("hello", hlua::LuaCode("return 5")).unwrap();

let r: i32 = lua.execute("return hello();").unwrap();
assert_eq!(r, 5);

Trait Implementations

impl<'a> Debug for LuaCode<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'lua, 'c, L> Push<L> for LuaCode<'c>

where L: AsMutLua<'lua>,

type Err = LuaError

Error that can happen when pushing a value.

fn push_to_lua(self, lua: L) -> Result<PushGuard<L>, (LuaError, L)>

Pushes the value on the top of the stack.

fn push_no_err<E>(self, lua: L) -> PushGuard<L>

where Self: Sized + Push<L, Err = E>, E: Into<Void>,

Same as push_to_lua but can only succeed and is only available if Err is Void.

impl<'lua, 'c, L> PushOne<L> for LuaCode<'c>

where L: AsMutLua<'lua>,
