Struct Span 

pub struct Span {
    pub offset: usize,
    pub len: usize,
    pub line: usize,
    pub col: usize,
}

Byte-level location in source text.

Fields

offset: usize

Byte offset from the start of the source.

len: usize

Length in bytes.

line: usize

Line number (1-based).

col: usize

Column number (1-based, in bytes).

Implementations

impl Span

pub fn new(offset: usize, len: usize, line: usize, col: usize) -> Span

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<(), Error>

Formats the value using the given formatter.

impl Display for Span

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

Formats the value using the given formatter.

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.
