• Parsing of attributes on statements
• Parsing of where clauses on type aliases
• Parsing of left-to-right mark and right-to-left mark codepoints
• Parsing of placement syntax
• Parsing of shebang at the top of a file

0.10.0-rc1

Release 0.10.0-rc1

0.9.2

• Add syn::parse_token_trees to parse tokens from a string. Token trees are much simpler than an AST. This makes them easier to work with when they are sufficient for the task at hand, such as for example expanding a function-like macro. (#52, thanks @SimonSapin)

0.9.1

• Make the fields of syn::Crate public (1271b29)
• Fixes to parsing of tokens within a macro invocation (f7922e3 and e6042a6)
• Parsing of byte and char literals (615cf6a)

0.9.0

• Enum discriminant values and array lengths now support expressions instead of just usize literals (#31).
• Update quote dependency to 0.3. Make sure to check those release notes for an important update affecting repetitions.
• Lots of progress on parsing Rust syntax beyond structs and enums (#4).

0.8.7

• Add Generics::split_for_impl which simplifies the handling of complex generic type signatures in a trait impl.

let (impl_generics, ty_generics, where_clause) = generics.split_for_impl();

quote! {
    impl #impl_generics MyTrait for #name #ty_generics #where_clause {
        // ...
    }
}
