Maintains stack trace and import resolution

Implementations

impl EvaluationState

pub fn add_file(&self, path: Rc<Path>, source_code: IStr) -> Result<()>

Parses and adds file as loaded

pub fn add_parsed_file(
    &self,
    name: Rc<Path>,
    source_code: IStr,
    parsed: LocExpr
) -> Result<()>

Adds file by source code and parsed expr

pub fn get_source(&self, name: &Path) -> Option<IStr>

pub fn map_source_locations(
    &self,

    locs: &[usize]
) -> Vec<CodeLocation>

pub fn with_stdlib(&self) -> &Self

pub fn push<T>(
    &self,
    e: Option<&ExprLocation>,
    frame_desc: impl FnOnce() -> String,
    f: impl FnOnce() -> Result<T>
) -> Result<T>

Executes code creating a new stack frame

pub fn run_in_state<T>(&self, f: impl FnOnce() -> T) -> T

pub fn with_tla(&self, val: Val) -> Result<Val>

If passed value is function then call with set TLA
