Callbacks used during the parsing process to indicate possible errors.

Provided Methods

fn unknown_content(&mut self, _text: &str, _span: Span)

The parser encountered some text it wasn’t able to make sense of.

fn gcode_buffer_overflowed( &mut self, _mnemonic: Mnemonic, _major_number: u32, _minor_number: u32, _arguments: &[Word], _span: Span, )

The Buffers::Commands buffer had insufficient capacity when trying to add a GCode.

fn gcode_argument_buffer_overflowed( &mut self, _mnemonic: Mnemonic, _major_number: u32, _minor_number: u32, _argument: Word, )

The Buffers::Arguments buffer had insufficient capacity when trying to add a Word.

To aid in diagnostics, the caller is also given the GCode’s mnemonic and major/minor numbers.

fn comment_buffer_overflow(&mut self, _comment: Comment<'_>)

A Comment was encountered, but there wasn’t enough room in Buffers::Comments.

fn unexpected_line_number(&mut self, _line_number: f32, _span: Span)

A line number was encountered when it wasn’t expected.

fn argument_without_a_command( &mut self, _letter: char, _value: f32, _span: Span, )

An argument was found, but the parser couldn’t figure out which GCode it corresponds to.

fn number_without_a_letter(&mut self, _value: &str, _span: Span)

A Word’s number was encountered without an accompanying letter.

fn letter_without_a_number(&mut self, _value: &str, _span: Span)

A Word’s letter was encountered without an accompanying number.
