Struct hlua::InsideCallback

pub struct InsideCallback { /* private fields */ }

Opaque type that represents the Lua context when inside a callback.

Some types (like Result) can only be returned from a callback and not written inside a Lua variable. This type is here to enforce this restriction.

Trait Implementations

impl<'a, 'lua> AsLua<'lua> for &'a InsideCallback

fn as_lua(&self) -> LuaContext

impl<'a, 'lua> AsLua<'lua> for &'a mut InsideCallback

fn as_lua(&self) -> LuaContext

impl<'a, 'lua> AsMutLua<'lua> for &'a mut InsideCallback

fn as_mut_lua(&mut self) -> LuaContext

Returns the raw Lua context.

impl Debug for InsideCallback

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

Formats the value using the given formatter.

impl<'a, T, E, P> Push<&'a mut InsideCallback> for Result<T, E>

where T: Push<&'a mut InsideCallback, Err = P> + for<'b> Push<&'b mut &'a mut InsideCallback, Err = P>, E: Display,

type Err = P

Error that can happen when pushing a value.

fn push_to_lua( self, lua: &'a mut InsideCallback ) -> Result<PushGuard<&'a mut InsideCallback>, (P, &'a mut InsideCallback)>

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<'a, T, E, P> PushOne<&'a mut InsideCallback> for Result<T, E>

where T: PushOne<&'a mut InsideCallback, Err = P> + for<'b> PushOne<&'b mut &'a mut InsideCallback, Err = P>, E: Display,
