auto_enums

• 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.)

• Improved error messages.

• Updated proc-macro2, syn, and quote to 1.0.

• Updated derive_utils to 0.9. This improves the error message.

• Added some generated code examples.

• Updated to support futures-preview 0.3.0-alpha.17.

• Added some generated code examples.

• Added support for futures::io::{AsyncSeek, AsyncBufRead}.

• Updated to new nightly. iovec stabilized. #[enum_derive] automatically detects the rustc version and supports Read::read_vectored and Write::write_vectored as the part of Read and Write.

• Supported for latest futures 0.3.0-alpha.16.

• Updated to new nightly.

• Fixed trait support in "type_analysis" feature.

• Fixed the problem that "failed to resolve: use of undeclared type or module" (E0433) error is shown when one or more compilation errors occur when multiple #[auto_enum] attributes are used.

• Improved the error message of #[enum_derive] attribute.

• Updated minimum derive_utils version to 0.7.0. This improves the error message.

• Greatly improved the error message of #[auto_enum] attribute.

• Added some generated code examples.

• Added "iovec" crate feature. This supports the unstable iovec feature (https://github.com/rust-lang/rust/issues/58452).

• Updated minimum syn version to 0.15.29. This fixes some warnings.

• Fixed examples and some sentence in README.md.

• Transition to Rust 2018. With this change, the minimum required version will go up to Rust 1.31.

• Reduced the feature of "std" crate feature. The current "std" crate feature only determines whether to enable std library's traits (e.g., std::io::Read) support. "std" crate feature is enabled by default, but you can reduce compile time by disabling this feature.

• Fixed problem where "macro attributes must be placed before #[derive]" error occurred when #[enum_derive] attribute was used with other attributes.

• No longer need #[macro_use] extern crate auto_enums;. You can use #[auto_enum] attribute by use auto_enums::auto_enum;.

• Removed "unstable" crate feature.
