* Static methods no longer require the `static` keyword and instead
are distinguished by the lack of a `self` parameter
2013-03-12 02:27:41 +01:00
* Replaced the `Durable` trait with the `'static` lifetime
* The old closure type syntax with the trailing sigil has been
removed in favor of the more consistent leading sigil

* Traits are implemented with `impl Trait for Type`
instead of `impl Type: Trait`
2013-03-26 20:28:04 +01:00

* The interior mutability qualifier on vectors, `[mut T]`, has been
removed. Use `&mut [T]`, etc.

function modules. Use extern blocks: `extern { ... }`
* Newtype enums removed. Use tuple-structs.

* Casts to traits must use a pointer sigil, e.g. `@foo as @Bar`
instead of `foo as Bar`.
* Fixed length vector types are now written as `[int, .. 3]`
instead of `[int * 3]`.
* Fixed length vector types can express the length as a constant
expression. (ex: `[int, .. GL_BUFFER_SIZE - 2]`)
2013-03-12 02:27:41 +01:00
* Semantic changes
* Types with owned pointers or custom destructors move by default,
eliminating the `move` keyword
