Expand description
An extension trait for Table
s that provides a variety of convenient functionality.
Required Methods§
sourcefn call<A, R>(&self, args: A) -> Result<R, Error>where
A: IntoLuaMulti<'lua>,
R: FromLuaMulti<'lua>,
fn call<A, R>(&self, args: A) -> Result<R, Error>where
A: IntoLuaMulti<'lua>,
R: FromLuaMulti<'lua>,
Calls the table as function assuming it has __call
metamethod.
The metamethod is called with the table as its first argument, followed by the passed arguments.
sourcefn call_method<A, R>(&self, name: &str, args: A) -> Result<R, Error>where
A: IntoLuaMulti<'lua>,
R: FromLuaMulti<'lua>,
fn call_method<A, R>(&self, name: &str, args: A) -> Result<R, Error>where
A: IntoLuaMulti<'lua>,
R: FromLuaMulti<'lua>,
Gets the function associated to key
from the table and executes it,
passing the table itself along with args
as function arguments.
This is a shortcut for
table.get::<_, Function>(key)?.call((table.clone(), arg1, ..., argN))
This might invoke the __index
metamethod.
sourcefn call_function<A, R>(&self, name: &str, args: A) -> Result<R, Error>where
A: IntoLuaMulti<'lua>,
R: FromLuaMulti<'lua>,
fn call_function<A, R>(&self, name: &str, args: A) -> Result<R, Error>where
A: IntoLuaMulti<'lua>,
R: FromLuaMulti<'lua>,
Gets the function associated to key
from the table and executes it,
passing args
as function arguments.
This is a shortcut for
table.get::<_, Function>(key)?.call(args)
This might invoke the __index
metamethod.
Object Safety§
This trait is not object safe.
