//! Semantic marker trait for buffered encoders.

use super::BufferedTranscoder;

/// Encodes logical values into encoded units over caller-provided buffers.
///
/// `BufferedEncoder` refines [`BufferedTranscoder`] for implementations whose input is
/// the logical value stream and whose output is the encoded unit stream. The
/// trait adds no methods; it exists to make generic bounds distinguish encoding
/// direction from decoding and unit-to-unit conversion.
///
/// The word "buffered" describes the caller-managed buffer and progress model.
/// It does not require the implementor to own an internal buffer.
///
/// # Type Parameters
///
/// - `Value`: Logical value type accepted by the encoder.
/// - `Unit`: Encoded unit type produced by the encoder.
pub trait BufferedEncoder<Value, Unit>: BufferedTranscoder<Value, Unit> {}
