entry

The decorator @entry on a function marks that function as an entrypoint of the contract, either at top-level or in a module that is then used as a contract. Here is an example of entrypoints defined in a module:

type storage = int;

type @return = [list<operation>, storage];

namespace Foo {

@entry

const decrement = (param: int, storage: storage) : @return =>

[[], storage - param];

@entry

const increment = (param: int, storage: storage) : @return =>

[[], storage + param];

@entry

const reset = (_u: unit, _s: storage) : @return =>

[[], 0];

@view

const get_storage = (_: unit, storage: storage) : storage => storage;

};

Note that if you want to define an entrypoint called default, use the escaped identifier @default because default is a keyword.
