Struct Span 

pub struct Span {
    pub start: usize,
    pub end: usize,
}

Byte offset range in source text. Attached to every AST node so diagnostics can point at the exact source location.

Fields

start: usize

end: usize

Implementations

impl Span

pub fn new(start: usize, end: usize) -> Self

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

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 Serialize for Span

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
