pub struct EvalCtx { /* private fields */ }

Implementations

impl EvalCtx

pub fn new_empty() -> Self

pub fn new_in_mode(mode: EvalMode) -> Result<Self>

Initialize a new EvalCtx with set up modules and module resolver.

The given mode is used when initializing the io module, to determine whether to actually perform any IO or to just simulate it.

pub fn set_module_path(&mut self, path: &Path)

Set the directory to look for imports in.

The given path is used as the path for the a FileModuleResolver, such that import statements can be used in rhai code relative to this path.

pub fn load_rhai_file_to_module( &mut self, content: &str, ) -> Result<(), RhaiError>

Load a given rhai string as a global module, and store it as the yolk_file_module.

pub fn eval_rhai<T: Variant + Clone>( &mut self, content: &str, ) -> Result<T, RhaiError>

Eval a given string of rhai and return the result. Execute in the scope of this EvalCtx.

pub fn eval_text_transformation( &mut self, text: &str, expr: &str, ) -> Result<String, RhaiError>

Eval a rhai expression in a scope that has a special get_yolk_text() function that returns the given text. After the expression is evaluated, the scope is rewound to its state before the function was added.

pub fn set_global<T: Variant + Clone>(&mut self, name: &str, value: T)

pub fn engine_mut(&mut self) -> &mut Engine

pub fn yolk_file_module(&self) -> Option<&Arc<Module>>
