2013-03-26 19:28:04 +00:00

|
2013-03-12 01:27:41 +00:00
|
|
|
|
|
|
|
* Syntax changes
|
|
|
|
* The self type parameter in traits is now spelled `Self`
|
2013-03-22 18:59:59 +00:00
|
|
|
* The `self` parameter in trait and impl methods must now be explicitly
|
|
|
|
named (for example: `fn f(&self) { }`). Implicit self is deprecated.
|
2013-03-26 19:28:04 +00:00
|
|
|
* Static methods no longer require the `static` keyword and instead
|
|
|
|
are distinguished by the lack of a `self` parameter
|
2013-03-12 01:27:41 +00:00
|
|
|
* 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
|
|
|
|
* `super` is a keyword, and may be prefixed to paths
|
|
|
|
* Trait bounds are separated with `+` instead of whitespace
|
|
|
|
* Traits are implemented with `impl Trait for Type`
|
|
|
|
instead of `impl Type: Trait`
|
2013-03-26 19:28:04 +00:00
|
|
|
* Lifetime syntax is now `&'l foo` instead of `&l/foo`
|
2013-03-12 01:27:41 +00:00
|
|
|
* The `export` keyword has finally been removed
|
2013-03-22 18:59:59 +00:00
|
|
|
* The `move` keyword has been removed (see "Semantic changes")
|
2013-03-12 01:27:41 +00:00
|
|
|
* The interior mutability qualifier on vectors, `[mut T]`, has been
|
|
|
|
removed. Use `&mut [T]`, etc.
|
|
|
|
* `mut` is no longer valid in `~mut T`. Use inherited mutability
|
|
|
|
* `fail` is no longer a keyword. Use `fail!()`
|
|
|
|
* `assert` is no longer a keyword. Use `assert!()`
|
|
|
|
* `log` is no longer a keyword. use `debug!`, etc.
|
|
|
|
* 1-tuples may be represented as `(T,)`
|
|
|
|
* Struct fields may no longer be `mut`. Use inherited mutability,
|
|
|
|
`@mut T`, `core::mut` or `core::cell`
|
|
|
|
* `extern mod { ... }` is no longer valid syntax for foreign
|
|
|
|
function modules. Use extern blocks: `extern { ... }`
|
|
|
|
* Newtype enums removed. Used tuple-structs.
|
|
|
|
* Trait implementations no longer support visibility modifiers
|
2013-03-22 18:59:59 +00:00
|
|
|
* Pattern matching over vectors improved and expanded
|
2013-03-22 19:41:42 +00:00
|
|
|
* `const` renamed to `static` to correspond to lifetime name,
|
|
|
|
and make room for future `static mut` unsafe mutable globals.
|
2013-03-26 19:28:04 +00:00
|
|
|
* Replaced `#[deriving_eq]` with `#[deriving(Eq)]`, etc.

* `Clone` implementations can be automatically generated with
|
|
|
|
`#[deriving(Clone)]`
|
2013-03-26 19:28:04 +00:00
|
|
|
* Casts to traits must use a pointer sigil, e.g. `@foo as @Bar`
|
|
|
|
instead of `foo as Bar`.
|

|
|
|
* Semantic changes
|
2013-03-13 20:47:49 +00:00
|
|
|
* Types with owned pointers or custom destructors move by default,

|
|
|
eliminating the `move` keyword

2013-03-12 01:27:41 +00:00
|
|
|
* All foreign functions are considered unsafe

|
|
|

|
|
|
|
* () has size 0
|
|
|
|
* The name of the main function can be customized using #[main]
|
|
|
|
* The default type of an inferred closure is &fn instead of @fn
|
2013-03-26 19:28:04 +00:00
|
|
|
* `use` statements may no longer be "chained" - they cannot import
|
|
|
|
identifiers imported by previous `use` statements
|
|
|
|
* `use` statements are crate relative, importing from the "top"
|
|
|
|
of the crate by default. Paths may be prefixed with `super::`
|
|
|
|
or `self::` to change the search behavior.
|
2013-03-12 01:27:41 +00:00

improve inference and eliminate unsoundness
|
2013-03-26 20:56:49 +00:00

|
|
* Macros leave scope at the end of modules, unless that module is
|
|
|
|
tagged with #[macro_escape]
