Struct Span 

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

A byte offset and length in the input, for error reporting.

Span tracks the location of errors within the original input string, enabling precise error messages for diagnostic tools.

use pkgsrc_kv::Span;

let span = Span { offset: 10, len: 5 };
let range: std::ops::Range<usize> = span.into();
assert_eq!(range, 10..15);

Fields

offset: usize

Byte offset where this span starts.

len: usize

Length in bytes.

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 Copy for Span

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 Eq for Span

impl From<Span> for Range<usize>

fn from(span: Span) -> Self

Converts to this type from the input type.

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.
