iab-specs-core

Core types, traits, and error handling for the iab-specs ecosystem.

Overview

This crate provides the shared foundation used by all iab-specs-* sub-crates:

• Extension trait — Marker trait for type-safe extension fields on IAB specification objects. Any type implementing Serialize + Deserialize + Clone + Debug + Default + PartialEq + Send + Sync automatically satisfies Extension.
• DefaultExt — Type alias for Vec<u8>, the default opaque-byte extension type.
• Error / Result — Shared error types covering builder errors, serialization errors, and invalid state transitions.
• slice_up_to! — Macro for safe sub-slicing without panics.

Features

• serde_json — Enables the SerdeJsonError variant in Error (wraps serde_json::Error).
