Struct Span 

pub struct Span {
    pub line: u32,
    pub col: u32,
    pub offset: usize,
    pub len: usize,
}

Source location for diagnostics.

Tracks the line, column, byte offset, and length of a token or construct in the original assembly source text.

Fields

line: u32

1-based line number.

col: u32

1-based column number (byte offset within line).

offset: usize

0-based byte offset from start of source.

len: usize

Byte length of the spanned region.

Implementations

impl Span

pub fn new(line: u32, col: u32, offset: usize, len: usize) -> Self

Create a new span.

pub fn dummy() -> Self

A dummy span for generated/internal constructs.

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 Display for Span

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

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.

impl Copy for Span

impl Eq for Span
