Struct quad_compat_rhai::EvalState

pub struct EvalState {
    pub always_search_scope: bool,
    pub scope_level: usize,
    // some fields omitted
}

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

Fields

always_search_scope: 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, or after a custom syntax statement, subsequent offsets may become mis-aligned. When that happens, this flag is turned on to force a Scope search 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.

Implementations

impl EvalState

pub const fn new() -> Self

Create a new EvalState.

pub const fn is_global(&self) -> bool

Is the state currently at global (root) level?

pub fn fn_resolution_caches_len(&self) -> usize

Get the number of function resolution cache(s) in the stack.

pub fn fn_resolution_cache_mut(&mut self) -> &mut FnResolutionCache

Get a mutable reference to the current function resolution cache.

pub fn push_fn_resolution_cache(&mut self)

Push an empty function resolution cache onto the stack and make it current.

pub fn rewind_fn_resolution_caches(&mut self, len: usize)

Rewind the function resolution caches stack to a particular size.
