Struct Loc 

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

Source location (1-based line and column) attached to select AST nodes for diagnostics.

Loc is intentionally transparent to equality and serialization: two nodes that differ only in location compare equal, and the position is never written to the serialized AST (the field carries #[serde(skip)]).

Fields

line: u32

column: u32

Implementations

impl Loc

pub fn new(line: u32, column: u32) -> Self

pub fn position(&self) -> Option<(u32, u32)>

The tracked (line, column), or None when unknown (line 0).

pub fn line(&self) -> Option<u32>

The tracked line, or None when unknown (line 0).
