Struct ketos::buffer::CodeBuffer

pub struct CodeBuffer { /* fields omitted */ }

Buffers potentially incomplete input code

Methods

impl CodeBuffer

fn new() -> CodeBuffer

Creates a CodeBuffer with an empty buffer

fn clear(&mut self)

Clears the input buffer.

fn feed_compile(&mut self,
                interp: &Interpreter,
                input: &str)
                -> Result<MoreResult<Vec<Code>>, Error>

Feeds some input to the buffer.

Input should be terminated with a newline ('\n').

Compilation will be attempted with the given interpreter. If parsing fails because more input is required, Ok(MoreResult::More(_)) will be returned, indicating the reason input is incomplete.

If some other error is encountered, it is returned. Otherwise, Ok(MoreResult::Complete(_)) is returned with compiled expressions.

If either Ok(MoreResult::Complete(_)) or Err(_) is returned, the input buffer is cleared after compiling.

fn feed_parse(&mut self,
              interp: &Interpreter,
              input: &str)
              -> Result<MoreResult<Vec<Value>>, Error>

Feeds some input to the buffer.

Like feed_compile, but the input is only parsed.
