v1.3.0

Version 1.3.0 released to crates.io.

This version adds native support for BLOB's (byte arrays), as well as a number of configuration settings to fine-tun language features.

Compiler requirement

• Minimum compiler version is now 1.51.

Bug fixes

• from_dynamic now supports deserializing Option.

New features

• BLOB (essentially a byte array) is added as a supported primitive value type parallel to arrays.
• New options for Engine which allows disabling if-expressions, switch-expressions, statement expressions, anonymous functions and/or looping (i.e. while, loop, do and for statements):
  • Engine::set_allow_if_expression
  • Engine::set_allow_switch_expression
  • Engine::set_allow_statement_expression
  • Engine::set_allow_anonymous_fn
  • Engine::set_allow_looping
• New strict variables mode for Engine (enabled via Engine::set_strict_variables) to throw parse errors on undefined variable usage. Two new parse error variants, ParseErrorType::VariableNotFound and ParseErrorType::ModuleNotFound, are added.

Enhancements

• Two double quotes ("") in a string literal now maps to "; two back-ticks (``) in a literal string now maps to `.
• Added Engine::register_type_with_name_raw to register a custom type based on a fully-qualified type path.
• Added into_array and into_typed_array for Dynamic.
• Added FnPtr::call and FnPtr::call_within_context to simplify calling a function pointer.
• A function's hashes are included in its JSON metadata to assist in debugging. Each function's baseHash field in the JSON object should map directly to the pre-calculated hash in the function call.
• Expression now derefs to Expr.

Deprecated and Gated API's

• NativeCallContext::new is deprecated because it is simpler to call a function pointer via FnPtr::call.
• AST::merge_filtered and AST::combine_filtered are no longer exported under no_function.
• AST::new and AST::new_with_source are moved under internals.
• FnPtr::call_dynamic is deprecated in favor of FnPtr::call_raw.
