Struct Span 

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

A source location in the document a node was read from.

Spans never take part in equality or hashing: two spans always compare equal.

Fields

line: u32

1-based line, or 0 when unknown.

column: u32

1-based column, or 0 when unknown.

Implementations

impl Span

pub const NONE: Span

The span of a node that was not read from a document.

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

A span at the given line and column.

pub const fn is_known(&self) -> bool

Whether this span carries a known position.
