Struct Location 

pub struct Location {
    pub file: Option<String>,
    pub line: u32,
    pub col: u32,
    pub span: [u32; 2],
}

Source location of a diagnostic — a 1-based line/column plus an absolute byte span.

file is the canonical path string; absent for synthetic / REPL diagnostics.

Fields

file: Option<String>

File path; absent for synthetic / REPL / in-memory sources.

line: u32

1-based line number.

col: u32

1-based column number.

span: [u32; 2]

Absolute byte span [start, end) into the source buffer.

Implementations

impl Location

pub fn new( file: Option<String>, line: u32, col: u32, span_start: u32, span_end: u32, ) -> Self

Construct a Location with a 1-based line/column and an absolute byte span.

pub fn synthetic() -> Self

Synthetic location with no file and zero positions — used for diagnostics not anchored to source (e.g., compiler-internal configuration errors).

Trait Implementations

impl Clone for Location

fn clone(&self) -> Location

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Location

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Location

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Location

fn eq(&self, other: &Location) -> 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.

impl Serialize for Location

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
