Syntax
- struct Foo { field1: Type1, field2: Type2 }
- let foo = Foo { field1: Type1::new(), field2: Type2::new() };
- struct Bar ( Type1, Type2 ); // tuple type
- let _ = Bar(Type1::new(), Type2::new());
- struct Baz; // unit-like type
- let _ = Baz;
- let Foo { field1, .. } = foo; // extract field1 by pattern matching
- let Foo { field1: x, .. } = foo; // extract field1 as x
- let foo2 = Foo { field1: Type1::new(), .. foo }; // construct from existing
- impl Foo { fn fiddle(&self) {} } // declare instance method for Foo
- impl Foo { fn tweak(&mut self) {} } // declare mutable instance method for Foo
- impl Foo { fn double(self) {} } // declare owning instance method for Foo
- impl Foo { fn new() {} } // declare associated method for Foo
