Rust Analyzer Syntax Trees Implementation - 2019 Overview

Explore the implementation of syntax trees in rust-analyzer through this comprehensive 57-minute video presentation. Dive into the public API, including enum API, expression API, and various node types. Learn about incremental updates, parsing techniques, and memory efficiency. Discover how to build Rust from the tree and understand token mapping. Gain valuable insights into the inner workings of rust-analyzer's syntax tree implementation, presented by @matklad in this recorded session from February 26, 2019.
