Struct Location 

pub struct Location {
    pub position: usize,
    pub line: usize,
    pub column: usize,
}

Represent a position in a source file.

Location represents the position of a single character or token in a source file, given by its position which is the actual index in the corresponding buffer, and a pair of line and column information.

Line and column information start from zero, but the Display instance of Location and Span show line numbers to the user as starting from one.

Fields

position: usize

The index of this location in the corresponding buffer

line: usize

The line number corresponding to this location

column: usize

The column number corresponding to this location
