Struct LineDirective 

pub struct LineDirective {
    pub span: Span,
    pub line: u32,
    pub file: Option<Symbol>,
    pub at: usize,
}

A #line directive, as read and as applied to the source map.

Fields

span: Span

Where the directive is.

line: u32

The line number the next line is to be called.

file: Option<Symbol>

The file name the following lines are to be called, if one was given.

at: usize

How many tokens had been emitted when this was read, which is where it sits in the stream.

A position is not enough to say that. A file included from here is added to the source map after this file, so its bytes come after every byte of this one, and the token after the #include is at a lower position than the tokens of the header. -E has to write a marker for a #line where the directive was written rather than where its bytes are, and this is what says where that is.
