Struct evcxr::CommandContext

pub struct CommandContext { /* private fields */ }

A higher level interface to EvalContext. A bit closer to a Repl. Provides commands (start with ‘:’) that alter context state or print information.

Implementations

impl CommandContext

pub fn new() -> Result<(CommandContext, EvalContextOutputs), Error>

pub fn with_eval_context(eval_context: EvalContext) -> CommandContext

pub fn execute(&mut self, to_run: &str) -> Result<EvalOutputs, Error>

pub fn check(&mut self, code: &str) -> Result<Vec<CompilationError>, Error>

pub fn process_handle(&self) -> Arc<Mutex<Child>>

pub fn variables_and_types(&self) -> impl Iterator<Item = (&str, &str)>

pub fn reset_config(&mut self)

pub fn defined_item_names(&self) -> impl Iterator<Item = &str>

pub fn execute_with_callbacks( &mut self, to_run: &str, callbacks: &mut EvalCallbacks<'_> ) -> Result<EvalOutputs, Error>

pub fn set_opt_level(&mut self, level: &str) -> Result<(), Error>

pub fn last_source(&self) -> Result<String>

pub fn completions(&mut self, src: &str, position: usize) -> Result<Completions>

Returns completions within src at position, which should be a byte offset. Note, this function requires &mut self because it mutates internal state in order to determine completions. It also assumes exclusive access to those resources. However there should be any visible side effects.
