Struct ParagraphMeta

pub struct ParagraphMeta {
    pub byte_range: Range<usize>,
    pub revision: u64,
}

Metadata for one paragraph: UTF-8 byte range and revision counter.

Paragraph ranges are half-open. A terminating newline belongs to the paragraph before it. A nonempty buffer ending in \n has no extra empty paragraph, while an entirely empty buffer has one 0..0 paragraph.

Examples

use ailloli_ui_text::ParagraphMeta;
let meta = ParagraphMeta { byte_range: 2..8, revision: 3 };
assert_eq!(meta.byte_range, 2..8);
assert_eq!(meta.revision, 3);

Fields

byte_range: Range<usize>

Half-open UTF-8 byte range in the complete buffer.

revision: u64

Wrapping revision assigned when this indexed paragraph was rebuilt.

Trait Implementations

impl Clone for ParagraphMeta

fn clone(&self) -> ParagraphMeta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParagraphMeta

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

Formats the value using the given formatter.

impl PartialEq for ParagraphMeta

fn eq(&self, other: &ParagraphMeta) -> 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.
