(INTERNALS) A type that holds all the current states of the Engine. Exported under the internals feature only.

WARNING

This type is volatile and may change.

Fields

source: Option<ImmutableString>

Source of the current context.

always_search: bool

Normally, access to variables are parsed with a relative offset into the scope to avoid a lookup. In some situation, e.g. after running an eval statement, subsequent offsets become mis-aligned. When that happens, this flag is turned on to force a scope lookup by name.

scope_level: usize

Level of the current scope. The global (root) level is zero, a new block (or function call) is one level higher, and so on.

operations: u64

Number of operations performed.

modules: usize

Number of modules loaded.

functions_cache: HashMap<NonZeroU64, Option<CallableFunction>, StraightHasherBuilder>

Cached lookup values for function hashes.
