Use descriptive, self-explanatory names for variables, methods, fields, and types. Avoid single-letter variables, abbreviations, and generic naming that obscures intent.

Key principles:

Example:

// Poor naming
let c = &item.response.customer;
let n = c.name.as_ref().map(|n| n.clone().expose());
pub customer_id: String,
pub payment_method: String,

// Good naming  
let customer = &item.response.customer;
let customer_name = customer.name.as_ref().map(|name| name.clone().expose());
pub customer_id: id_type::CustomerId,
pub payment_method: PaymentMethodType,

Clear, meaningful names reduce cognitive load, improve code maintainability, and make the codebase more accessible to new developers.
