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.

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
