Crate stack_any

stack-any

A library that provides a type that owns same size type on the stack for type erasure.

Usage

Same size type on the stack for type erasure.

let stack_0 = stack_any::stack_any!(Vec<i32>, vec![0, 1, 2]);
let stack_1 = stack_any::stack_any!(Vec<char>, vec!['a', 'b', 'c']);
let mut stacks = [stack_0, stack_1];

stacks[0].downcast_mut::<Vec<i32>>().push(3);
stacks[1].downcast_mut::<Vec<char>>().push('d');

assert_eq!(stacks[0].downcast_ref::<Vec<i32>>(), &vec![0, 1, 2, 3]);
assert_eq!(stacks[1].downcast_ref::<Vec<char>>(), &vec!['a', 'b', 'c', 'd']);

Different size type on the stack for type erasure.

let mut stack = stack_any::StackAny::<8>::new(0);

*stack.downcast_mut::<i32>() = 100;
assert_eq!(stack.downcast_ref::<i32>(), &100);

*stack.downcast_mut::<i64>() = 200;
assert_eq!(stack.downcast_ref::<i64>(), &200);

Macros

• stack_any
  Allocates memory on the stack and then places value based on given type and value.

Structs

• StackAny
  A convertible type that owns a stack allocation of N size.
