[−][src]Struct evalexpr::HashMapContext
A context that stores its mappings in hash maps.
Value and function mappings are stored independently, meaning that there can be a function and a value with the same identifier.
This context is type-safe, meaning that an identifier that is assigned a value of some type once cannot be assigned a value of another type.
