impl SqlHighlighter

pub fn new() -> Self

SQL only: other languages are plain text.

pub fn with_fallback(fallback: Arc<dyn CodeHighlighter>) -> Self

SQL here, every other language through fallback (syntect, lumis or another engine).

use std::sync::Arc;
use rich::protocol::CodeHighlighter;
use rich_ext::sql::SqlHighlighter;

let both = SqlHighlighter::with_fallback(Arc::new(SqlHighlighter::new()));
assert!(both.languages().contains(&"duckdb".to_string()));

pub fn shared() -> Arc<dyn CodeHighlighter>

One shared instance with no fallback.
