Summary by Sourcery

Document configurable framing by adding examples and detailed descriptions for the built-in LengthPrefixedProcessor and its LengthFormat configuration.

Documentation:

  • Add a Rust code snippet in the README showing how to set a custom length prefix (e.g., u16_le) with LengthPrefixedProcessor.
  • Update the library design documentation to describe the LengthPrefixedProcessor, its LengthFormat options, and the public FrameProcessor trait for custom implementations.

Summary by CodeRabbit

  • Documentation
    • Updated references to design document line numbers for improved accuracy.
    • Added a Rust code example demonstrating configuration of the WireframeApp with a length-prefixed processor.
    • Clarified documentation on built-in frame processing options and how to customise framing strategies.

Walkthrough

Documentation was updated to clarify and expand on the configuration of frame processing in the "wireframe" library, specifically describing the built-in LengthPrefixedProcessor and its usage with different prefix formats. References to design document line numbers were corrected, and a new Rust code example was added to illustrate custom framing configuration.

Changes

File(s) Change Summary
README.md Updated design document line references; added Rust example for configuring WireframeApp with LengthPrefixedProcessor.
docs/rust-binary-router-library-design.md Expanded documentation on built-in LengthPrefixedProcessor, its configuration, and clarified public API details.

Poem

A nibble, a byte, a frame in the night,
The docs now explain how to prefix just right.
With Rusty precision and framing anew,
Wireframe’s examples are clearer for you.
So hop along, coder, and prefix with glee—
This rabbit has documented framing for thee!

400-407: Built-in LengthPrefixedProcessor documentation is clear
The new section accurately describes configuring the built-in LengthPrefixedProcessor via

WireframeApp::frame_processor(LengthPrefixedProcessor::new(format))

This aligns well with the PR objectives and clarifies how to customize framing.

55-55: Verify doc reference for SharedState<T> extractor
Ensure the pointer docs/rust-binary-router-library-design.md†L622-L710 actually covers the SharedState<T> extractor section in the design doc.


86-86: Verify doc reference for binary protocol server example
Confirm that docs/rust-binary-router-library-design.md†L1126-L1156 correctly maps to the simple echo-server snippet.


92-92: Verify reference to response framing section
Please check that docs/rust-binary-router-library-design.md†L724-L730 points to the “Response Serialization and Framing” explanation.


97-97: Verify reference to default prefix configuration
Ensure the range L1082-L1123 covers the default 4-byte big-endian prefix details.


99-104: Confirm API signature for WireframeApp::new()
The snippet shows WireframeApp::new()?. Verify if .new() returns a Result; if not, remove the ? and explicitly import WireframeApp:

- let app = WireframeApp::new()?
+ let app = WireframeApp::new()

example, `LengthFormat::u16_le()` or `LengthFormat::u32_be()`. Applications
