Struct Loc 

pub struct Loc {
    pub file: FileId,
    pub line: u32,
    pub column: u32,
}

A position resolved back to a human coordinate.

Lines and columns both count from one, because that is what every editor, every other compiler and every user expects, and an off by one here is the kind of bug that survives for years because nobody quite trusts their own arithmetic enough to file it.

Fields

file: FileId

Which file.

line: u32

The line, counting from one.

column: u32

The column in bytes, counting from one.

Bytes rather than characters or display columns. A tab counts as one and a multibyte character counts as its encoded length, which is what a caret line drawn from the same bytes needs. -ftabstop and the width of a CJK character are the renderer’s problem; what belongs here is the offset into the line.
