Struct easy_repl::repl::Repl[−][src]

pub struct Repl<'a> { /* fields omitted */ }
Expand description

Read-eval-print loop.

REPL is ment do be constructed using the builder pattern via Repl::builder(). Commands are added during building and currently cannot be added/removed/modified after Repl has been built. This is because the names are used to generate Trie with all the names for fast name lookup and completion.

Repl can be used in two ways: one can use the Repl::run method directly to just start the evaluation loop, or Repl::next can be used to get back control between loop steps.

Implementations

impl<'a> Repl<'a>[src]

pub fn builder() -> ReplBuilder<'a>[src]

Start ReplBuilder with default values.

pub fn help(&self) -> String[src]

Returns formatted help message.

pub fn next(&mut self) -> Result<LoopStatus>[src]

Run a single REPL iteration and return whether this is the last one or not.

pub fn run(&mut self) -> Result<()>[src]

Run the evaluation loop until LoopStatus::Break is received.
