Struct Session 

pub struct Session { /* private fields */ }

One evaluation session.

Implementations

impl Session

pub fn new(config: Config) -> Self

pub fn interrupt_flag(&self) -> Arc<AtomicBool>

The flag that halts the running evaluation.

pub fn frame(&self) -> &Waku

pub fn reset(&mut self)

Forget every context and definition: a fresh interpreter, same frame.

pub fn load( &mut self, file: &Path, text: Option<&str>, how: Load, ) -> Outcome<Vec<String>>

Load file (its text from text when given, else from disk) as a fresh context, replacing any earlier load of it. Answers the names the file defines.

pub fn eval( &mut self, code: &str, file: Option<&Path>, budget: Option<usize>, ) -> Outcome<String>

Evaluate code in file’s context (loading its definitions first if it is not loaded), or the session’s own when file is None. Answers the value of the last form as canonical blue text.

pub fn expand( &mut self, code: &str, file: Option<&Path>, step: Step, ) -> Outcome<String>

Expand the macro call code one step or fully, in file’s context or the session’s.

pub fn complete(&self, prefix: &str, file: Option<&Path>) -> Vec<Item>

Every name prefix completes to in file’s context (or the session’s), each with its namespace and doc line.

pub fn doc(&self, name: &str, file: Option<&Path>) -> Option<Item>

What name is in file’s context (or the session’s): the first binding the resolution order reaches. pkg::name names a bidama’s definition and blue::name the builtin.
