Release notes

Sourced from syn's releases.

1.0.22

• Parse literal suffix on byte string, byte, and char literal tokens: br#"..."#suffix, b'?'suffix, '?'suffix (#799, #800)

1.0.21

• Documentation improvements

1.0.20

• Improve span of error message when an error during syn::Macro::parse_body is triggered past the last token of the macro body (#791)

1.0.19

• Parse a more lenient extern type syntax inside extern blocks (#763)

1.0.18

• Ignore unparsed empty None-delimited groups at the end of a macro input (#783)

1.0.17

• Expose syn::Lit in default-features = false mode

1.0.16

• Fix parsing of &raw raw reference operator (rust-lang/rust#64490) to require explicitly specified constness, &raw mut or &raw const

1.0.15

• Add Punctuated::first_mut to return a mut reference to the first sequence element

1.0.14

• Produce more helpful error messages from Attribute::parse_args

1.0.13

• Allow parse_quote! to parse Vec<Stmt>, with the same behavior as Block::parse_within (#741)

1.0.12

• Reject function signatures with an incorrectly placed receiver parameter, like fn f(x: u8, &self)
• Produce correctly spanned error when parsing punct beyond the end of a delimited group (#739)

1.0.11

• Implement quote::IdentFragment for syn::Member and syn::Index so that spans are preserved when using these types in quote's format_ident! macro

  use quote::format_ident;
  use syn::Index;
  let index: Index = /* ... */;
  let ident = format_ident!("__{}", index); // produces __0, __1, etc
  

1.0.10

• Provide Hash and Eq impls for syn::Member even without "extra-traits" feature enabled, as this type is commonly useful in a hashset

1.0.9

• Fix failure to parse tuple struct fields of tuple type starting with crate (#720, #723, thanks @mystor)

... (truncated)
