Struct SourceLocation 

pub struct SourceLocation {
    pub file: Option<String>,
    pub line: usize,
    pub column: usize,
    pub length: usize,
    pub end_line: Option<usize>,
    pub end_column: Option<usize>,
}

Source location information for error reporting

Fields

file: Option<String>

Source file path (if available)

line: usize

Line number (1-indexed)

column: usize

Column number (1-indexed)

length: usize

Length of the error span

end_line: Option<usize>

End line for multi-line spans

end_column: Option<usize>

End column for multi-line spans

Implementations

impl SourceLocation

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

Create a new source location

pub fn with_file(file: impl Into<String>, line: usize, column: usize) -> Self

Create a source location with file information

pub fn with_length(self, length: usize) -> Self

Set the span length

pub fn with_end(self, end_line: usize, end_column: usize) -> Self

Set the end position for multi-line spans

pub fn is_valid(&self) -> bool

Check if this is a valid location

pub fn span_to(&self, end: &SourceLocation) -> Self

Create a span from start to end location

Trait Implementations

impl Clone for SourceLocation

fn clone(&self) -> SourceLocation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SourceLocation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SourceLocation

fn default() -> SourceLocation

Returns the “default value” for a type.

impl Display for SourceLocation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for SourceLocation

impl PartialEq for SourceLocation

fn eq(&self, other: &SourceLocation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
