Follow a String through moves, clones, function calls, and borrowing. Stack-and-heap diagrams connect Rust’s ownership rules to the memory-management model familiar to JVM developers.
Choose the right Rust string type and understand the boundaries between bytes, Unicode scalar values, and user-perceived characters. Includes String, &str, OsString, and CString examples.
A guide to Rust conditions and loops, including expression values, labelled breaks, iterators, and ranges. Correctly distinguish a branch value from returning from a function.
Group values with tuples or arrays, access their elements, and destructure tuples. Learn the difference between a tuple’s length and standard-library trait support.
Choose between Rust’s integer, floating-point, boolean, and character types. The examples explain type widths, literal syntax, pointer-sized integers, and Unicode scalar values.
Learn Rust function syntax with small examples for typed parameters, return values, and tail expressions. Understand when a final expression returns a value.
A practical starting point for Rust: create a Cargo project, run it, and learn variables, mutability, constants, scope, and shadowing before moving to types and...
