Struct Location

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

Represents a location in the source code (position, line, column, length)

Fields

position: usize

The position in the source code (byte offset)

line: usize

The line number (1-based)

column: usize

The column number (1-based)

length: usize

The length of the token/node in characters

Implementations

impl Location

pub fn new(position: usize, line: usize, column: usize, length: usize) -> Self

Creates a new SourceLocation

Arguments

• position - Position in the source (byte offset)
• line - Line number (1-based)
• column - Column number (1-based)
• length - Length of the token/node in characters

Returns

A new SourceLocation

pub fn new_simple(position: usize, line: usize, column: usize) -> Self

Creates a new SourceLocation with the old 3-parameter signature for backward compatibility

Arguments

• position - Position in the source (byte offset)
• line - Line number (1-based)
• column - Column number (1-based)

Returns

A new SourceLocation with length = 1 (default for single character tokens)

pub fn end_position(&self) -> usize

Get the end position of this location

Returns

The byte offset position at the end of this location

pub fn end_column(&self) -> usize

Get the end column of this location (assuming single line)

Returns

The column number at the end of this location

pub fn span_to(&self, other: &Location) -> Location

Create a span from this location to another location

Arguments

• other - The other SourceLocation to create a span to

Returns

A new SourceLocation representing the span from this location to the other
