# GCFreeClosure

 A gc-free closure implementation for unity

 

 GC-Alloc has always been a kind of important performance measurement standard, so we should keep gc-alloc as less as possible.

 GCFreeClosure is designed for avoiding gc memory allocation.

 

 example:

 

```C#

//-----------------------------------------------------------------------------------

var action = ActionClosure.Create( ( a, b ) => UDebug.Print( a + b ), 1, 2 );

action.Invoke();

var function = FuncClosure.Create( ( a, b ) => a + b, 1, 2 );

var c = function.Invoke();

// use Tuple to pack multi-value together

var function2 = FuncClosure.Create( ctx => ctx.Item1 + ctx.Item2, STuple.Create( 1, 2 ) );

// call with return value

var c2 = function2.Invoke();

//-----------------------------------------------------------------------------------

var id = 1;

// system library implementation will cause gc-alloc for each function call.

list.FindIndex( e => e == id );

// replace system implementation to avoid gc-alloc

list.FindIndex( ( _id, e ) => e == _id, id );

```
