Struct ScanItem 

#[non_exhaustive]
pub struct ScanItem<'a> {
    pub raw: &'a str,
    pub span: Range<usize>,
    pub kind: ScanKind,
}

A single item produced by the scanner, carrying its raw source slice and a structural classification.

Concatenating all raw slices from a scan reconstructs the original input exactly.

Examples

use evfmt::{ScanKind, scan};

let item = scan("\u{00A9}").next().unwrap();
assert_eq!(item.raw, "\u{00A9}");
assert_eq!(item.span, 0.."\u{00A9}".len());
assert!(matches!(item.kind, ScanKind::EmojiSequence(_)));

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

raw: &'a str

The raw source text for this item.

span: Range<usize>

Byte range of this item in the original input.

kind: ScanKind

Structural classification of this item.

Trait Implementations

impl<'a> Clone for ScanItem<'a>

fn clone(&self) -> ScanItem<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for ScanItem<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for ScanItem<'a>

fn eq(&self, other: &ScanItem<'a>) -> 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.
