Struct Span 

pub struct Span {
    pub offset: u32,
    pub len: u32,
}

A byte-offset span in source text.

Fields

offset: u32

Byte offset of the start.

len: u32

Byte length.

Implementations

impl Span

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

pub fn end(&self) -> u32

pub fn merge(self, other: Span) -> Span

Merge two spans into one covering both.

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 Hash for Span

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
