Crate garnish_lang_traits

This crate contains interfaces and helper functions used by the Garnish Core libraries.

Modules

• helpers
  Helper functions created for core libraries that don’t have an implementation of GarnishData. These might be removed when an iterator interface is created for reading data instead of manual indexing.

Structs

• EmptyContext
  Concrete object for when a runtime requires no context functionality. Can use constants EMPTY_CONTEXT and NO_CONTEXT if needed as type parameters.
• RuntimeError
  Error implementation for crate::GarnishRuntime instruction methods.

Enums

• ErrorType
  List of possible error types a RuntimeError can be categorized as.
• GarnishDataType
  List of Garnish data types.
• Instruction
  List of possible instructions a Garnish runtime can process.

Constants

• EMPTY_CONTEXT
  Constant instantiation of EmptyContext.
• NO_CONTEXT
  An Option set to None. Typed as a mutable reference to an EmptyContext for use in crate::GarnishRuntime instruction methods that require a context be passed.

Traits

• GarnishContext
  Functionality required by Garnish contexts.
• GarnishData
  Trait defining what a data access operations are required by a runtime.
• GarnishNumber
  Arithmetic operations required so a runtime can resolve associated instruction.
• GarnishRuntime
  Trait containing instruction operations Garnish needs to execute. All instruction methods (e.g. all except GarnishRuntime::get_data, GarnishRuntime::get_data_mut should a Result. With the Ok value being the next instruction address to be executed if not sequential, otherwise return None
• TypeConstants
  Trait to provide constant values that a runtime will need access to.
