Trait CodeMapper 

pub trait CodeMapper {
    // Required methods
    fn lookup_char_pos(&self, pos: BytePos) -> Loc;
    fn span_to_lines(&self, sp: Span) -> FileLinesResult;
    fn span_to_string(&self, sp: Span) -> String;

}

Required Methods

fn lookup_char_pos(&self, pos: BytePos) -> Loc

fn span_to_lines(&self, sp: Span) -> FileLinesResult

fn span_to_string(&self, sp: Span) -> String

fn span_to_filename(&self, sp: Span) -> FileName

fn merge_spans(&self, sp_lhs: Span, sp_rhs: Span) -> Option<Span>
