1//! Message content types.
2//!
3//! The `ContentBlock` union + leaf content structs are canonically defined in
4//! [`turbomcp_types`] as of v3.2. `ContentBlock` is a type alias over
5//! [`turbomcp_types::Content`] so the two names refer to the same Rust type.
6//!
7//! # Content types
8//!
9//! - [`TextContent`], [`ImageContent`], [`AudioContent`] — inline content
10//! - [`ResourceLink`] — reference to an external resource
11//! - [`EmbeddedResource`] + [`ResourceContents`] (plural, `Text | Blob` union)
12//! - `ResourceContent` — backward-compatibility alias for [`ResourceContents`]
13//! - [`ContentType`] — `Json | Binary | Text` (turbomcp-internal; not MCP spec)
