Struct Span 

pub struct Span {
    pub line: usize,
    pub column: usize,
    pub length: usize,
}

Source span for a single token or expression

Fields

line: usize

Line number (0-indexed)

column: usize

Start column (0-indexed)

length: usize

Length of the span in characters

Implementations

impl Span

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

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 Debug for Span

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

Formats the value using the given formatter.

impl Default for Span

fn default() -> Span

Returns the “default value” for a type.

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.
