1//! Duplex Sponge Interface
2//!
3//! This module defines the [`DuplexSpongeInterface`] trait, which provides
4//! a generic interface for cryptographic sponge functions that support
5//! duplex operations: alternating absorb and squeeze phases.

12/// A trait defining the behavior of a duplex sponge construction.
13///
14/// A duplex sponge allows for:
15/// - **Absorbing** input data into the sponge state
16/// - **Squeezing** output data from the sponge state
17///
18/// This is the core primitive used for building cryptographic codecs.

20    /// Creates a new sponge instance with a given initialization vector (IV).
21    ///
22    /// The IV enables domain separation and reproducibility between parties.
