auto_enums

• Update derive_utils to 0.11.

• Add support for tokio03::{AsyncRead, AsyncWrite, AsyncSeek, AsyncBufRead}.

• Fix panic when multiple errors occur.

• Diagnostic improvements.

• type_analysis feature can now support impl trait in bindings.

  #[auto_enum]
  fn foo(x: i32) {
    // Unlike `feature(impl_trait_in_bindings)`, this works on stable compilers.
    #[auto_enum]
    let iter: impl Iterator<Item = i32> = match x {
        0 => Some(0).into_iter(),
        _ => 0..x,
    };
  }
  

• Updated derive_utils to 0.10.

• Fixed an issue that #[auto_enum] on non-statement expression does not work without unstable features.

• Added support for tokio02::{AsyncRead, AsyncWrite, AsyncSeek, AsyncBufRead}.

• Added support for tokio01::{AsyncRead, AsyncWrite}.

• Added futures03 feature. This is an alias of futures feature.

• Fix unused braces warnings

• Update to support latest generator

• Updated to support futures 0.3.0. (futures feature is no longer unstable)

• Support #[nested] for nested if expressions.

• Fixed bugs of "type_analysis" feature.

• Removed unstable "exact_size_is_empty", "read_initializer", and "try_trait" crate features.

• Updated to support futures-preview 0.3.0-alpha.19.

• Removed usage of mutable global state from #[auto_enum] for forward compatibility. See also rust-lang/rust#63831.

• Fixed links to generated code.

• Improved documentation.

• Added "unstable" crate feature to separate unstable features from stable features. When using features that depend on unstable APIs, the "unstable" feature must be explicitly enabled.

• Improved compile time.

• Renamed #[rec] to #[nested].

• Removed marker(name) option in favor of marker = name.

• Removed never option in argument position in favor of #[enum_derive] attribute.

• Removed "proc_macro" crate feature.

• Added "ops" crate feature, and made [std|core]::ops's Deref, DerefMut, Index, IndexMut, and RangeBounds traits optional.

• Added "convert" crate feature, and made [std|core]::convert's AsRef and AsMut traits optional.

• Added "generator_trait" crate feature, and made [std|core]::ops::Generator traits optional. (nightly-only)

• Added "fn_traits" crate feature, and made Fn, FnMut, and FnOnce traits optional. (nightly-only)

• Added "trusted_len" crate feature, and made [std|core]::iter::TrustedLen traits optional. (nightly-only)

• Improved error messages.

(There are no changes since the 0.6.0-alpha.3 release.)
