//! [`as_parser`]: turn a concrete parser type into `impl Parser + Clone` at the boundary.
//!
//! This lives outside [`super::capture`] so opaque-parser helpers stay separate from capture
//! machinery (`Capture`, binders, match results).

use crate::input::Input;
use crate::parser::{Parser, internal::ParserImpl};

/// Wraps a parser so call sites see `impl Parser` instead of a concrete combinator type.
///
/// Used by the [`crate::capture!`] macro and by hand-written grammars (for example the JSON
/// example) to introduce type-opacity boundaries.
