Struct Span 

pub struct Span {
    pub start: usize,
    pub end: usize,
    pub line: u32,
    pub col: u32,
}

A source-text span (zero-indexed byte offsets, 1-indexed line/column).

Lightweight and parser-library-agnostic — pest spans are converted to this shape at the parser/AST boundary so downstream code never sees pest types.

Fields

start: usize

end: usize

line: u32

col: u32

Implementations

impl Span

pub const fn synthetic() -> Self

A placeholder span for AST nodes synthesized by the planner (no source location).

pub fn is_synthetic(&self) -> bool

True if this span has no source location (was synthesized).

Trait Implementations

impl Clone for Span

fn clone(&self) -> Span

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Span

impl Debug for Span

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

Formats the value using the given formatter.

impl Display for Span

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

Formats the value using the given formatter.

impl Eq for Span

impl PartialEq for Span

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