0.7.0

Breaking changes

• Parser now requires BufRead rather than Read. This was already a practical requirement, given that it would have performed abysmally doing a syscall per byte if passed an unwrapped File.
• Added #[non_exhaustive] on Scope, Var, and ScopeItem.
• Added Vector type instead of using Vec<Value>. This is currently just a wrapper, but may be replaced with a faster bit vector in the future.
• Replaced InvalidData error type with ParseError and individual error types for FromStr implementations.
• Removed Header::comment field -- comments are now in items for consistency with child scopes and to allow multiple comments.
• Renamed Scope::children to items for consistency with Header and ScopeItem.
• Changed ReferenceIndex fields from u32 to i32.

Fixes

• Allow Header::find_var to find variables not under a scope.

Additions

• Track line number for error messages.
• Support $comment in scopes.
• Add access to the underlying io::BufRead on Parser.
• Add access to the underlying io::Write on Writer.
• Allow negative reference indexes.
• Improved documentation.
