source · [−]pub struct EvalContext<'a, 's, 'ps, 'm, 'pm, 'c, 't, 'pt> { /* private fields */ }Expand description
Context of a script evaluation process.
Implementations
sourceimpl EvalContext<'_, '_, '_, '_, '_, '_, '_, '_>
impl EvalContext<'_, '_, '_, '_, '_, '_, '_, '_>
sourcepub fn eval_expression_tree(
&mut self,
expr: &Expression<'_>
) -> Result<Dynamic, Box<EvalAltResult>>
pub fn eval_expression_tree(
&mut self,
expr: &Expression<'_>
) -> Result<Dynamic, Box<EvalAltResult>>
Evaluate an expression tree.
WARNING - Low Level API
This function is very low level. It evaluates an expression from an AST.

sourcepub fn scope_mut(&mut self) -> &mut &'s mut Scope<'ps>
pub fn scope_mut(&mut self) -> &mut &'s mut Scope<'ps>
Get a mutable reference to the current Scope.
sourcepub fn iter_imports(&self) -> impl Iterator<Item = (&str, &Module)>
pub fn iter_imports(&self) -> impl Iterator<Item = (&str, &Module)>
Get an iterator over the current set of modules imported via import statements,
in reverse order (i.e. modules imported last come first).
sourcepub fn tag_mut(&mut self) -> &mut Dynamic
pub fn tag_mut(&mut self) -> &mut Dynamic
Mutable reference to the custom state kept in a Dynamic.
sourcepub const fn global_runtime_state(&self) -> &GlobalRuntimeState<'_>
pub const fn global_runtime_state(&self) -> &GlobalRuntimeState<'_>
(internals) The current GlobalRuntimeState.
Exported under the internals feature only.
sourcepub fn global_runtime_state_mut(
&mut self
) -> &mut &'m mut GlobalRuntimeState<'pm>
pub fn global_runtime_state_mut(
&mut self
) -> &mut &'m mut GlobalRuntimeState<'pm>
(internals) Get a mutable reference to the current GlobalRuntimeState.
Exported under the internals feature only.
sourcepub fn iter_namespaces(&self) -> impl Iterator<Item = &Module>
pub fn iter_namespaces(&self) -> impl Iterator<Item = &Module>
Get an iterator over the namespaces containing definition of all script-defined functions.
sourcepub const fn namespaces(&self) -> &[&Module]
pub const fn namespaces(&self) -> &[&Module]
(internals) The current set of namespaces containing definitions of all script-defined functions.
Exported under the internals feature only.
sourcepub fn this_ptr_mut(&mut self) -> Option<&mut &'pt mut Dynamic>
pub fn this_ptr_mut(&mut self) -> Option<&mut &'pt mut Dynamic>
Mutable reference to the current bound this pointer, if any.
sourcepub const fn call_level(&self) -> usize
pub const fn call_level(&self) -> usize
The current nesting level of function calls.
