Rust Coding Guidelines (50 Core Rules)

Naming (Rust-Specific)

Rule
Guideline

No get_ prefix
fn name() not fn get_name()

Iterator convention
iter() / iter_mut() / into_iter()

Conversion naming
as_ (cheap &), to_ (expensive), into_ (ownership)

Static var prefix
G_CONFIG for static, no prefix for const

Data Types

Rule
Guideline

Use newtypes
struct Email(String) for domain semantics

Prefer slice patterns
if let [first, .., last] = slice

Pre-allocate
Vec::with_capacity(), String::with_capacity()

Avoid Vec abuse
Use arrays for fixed sizes
