Smash f-RustTrait-ion: Deep Dive on Send + Sync with Fledgio’s Lawrence Freeman

Join us at Rust Leeds for a high-energy deep dive into one of Rust’s most misunderstood topics - traits, and specifically, what it really means for a type to be Send and Sync.
Our speaker this month, Lawrence Freeman, founder of Fledgio and a Rust Foundation member, brings his trademark clarity and humour to an area that often leaves even seasoned Rustaceans scratching their heads.
Fledgio specialises in Rust training and upskilling, running public, corporate, and 1:1 courses, and their community channel, Rust Unwrapped, is currently running a popular Trait Deep Dive series.
This session will cover:

• What Send and Sync actually mean under the hood
• How they relate to ownership, threads, and the borrow checker
• The subtle difference between thread-safety and data race safety
• How marker traits work and why they exist
• How traits like Send, Sync, and 'static shape the type system’s guarantees

Bring your trait questions - we’ll round off with a Q&A discussing showing how these traits enforce safety without costing performance. https://www.fledgio.com/
