Lua::load and is used to finalize loading and executing Lua main chunks.
Sets the name of this chunk, which results in more informative error traces.
pub fn set_environment<V: ToLua<'lua>>(self, env: V) -> Result<Chunk<'lua, 'a>>[src]
Sets the first upvalue (
_ENV) of the loaded chunk to the given value.
Lua main chunks always have exactly one upvalue, and this upvalue is used as the
variable inside the chunk. By default this value is set to the global environment.
Calling this method changes the
_ENV upvalue to the value provided, and variables inside
the chunk will refer to the given environment rather than the global one.
All global variables (including the standard library!) are looked up in
_ENV, so it may be
necessary to populate the environment in order for scripts using custom environments to be
Execute this chunk of code.
This is equivalent to calling the chunk function with no arguments and no return values.
pub fn eval<R: FromLuaMulti<'lua>>(self) -> Result<R>[src]
Evaluate the chunk as either an expression or block.
If the chunk can be parsed as an expression, this loads and executes the chunk and returns
the value that it evaluates to. Otherwise, the chunk is interpreted as a block as normal,
and this is equivalent to calling
pub fn call<A: ToLuaMulti<'lua>, R: FromLuaMulti<'lua>>([src]
) -> Result<R>
) -> Result<R>
Load the chunk function and call it with the given arguemnts.
This is equivalent to
into_function and calling the resulting function.
pub fn into_function(self) -> Result<Function<'lua>>[src]
Load this chunk into a regular
This simply compiles the chunk without actually executing it.
