Struct SpellChecker 

pub struct SpellChecker {}

A handle to the host OS spell-checking service.

Implementations

impl SpellChecker

pub fn new() -> Self

Connect to the system spell checker. Always succeeds; on an unsupported platform — or if the OS service can’t be reached — the methods below just return empty results.

pub fn check(&self, text: &str) -> Vec<Range<usize>>

Find the misspelled words in text, returning their UTF-8 byte ranges (so &text[range] is the offending word). Cheap enough to run on edit.

Call on the main thread: the macOS backend talks to AppKit.

pub fn suggestions(&self, word: &str) -> Vec<String>

Suggested replacements for a single (presumably misspelled) word, best first. Potentially slow (a system spell-service round-trip on macOS) — call it lazily, for one word at a time, not across a whole document.

Call on the main thread.
