Prefer Rust’s built-in optional handling methods over manual checks and intermediate variables. Use if let Some(value) = option
for pattern matching, option.map(|x| x.field).unwrap_or(default)
for transformations with fallbacks, and option.is_some_and(|x| condition)
for conditional checks.
Instead of creating intermediate variables:
let is_recipe_execution = recipe.is_some();
let recipe_name_for_telemetry = recipe.clone().unwrap_or_default();
Use direct pattern matching:
if let Some(recipe_name) = recipe {
// use recipe_name directly
}
Instead of verbose match statements:
let recipe_version = match load_recipe(&name, params) {
Ok(recipe) => recipe.version,
Err(_) => "unknown".to_string(),
};
Use method chaining:
let recipe_version = load_recipe(&name, params)
.map(|r| r.version)
.unwrap_or_else(|| "unknown".to_string());
These patterns reduce boilerplate, improve readability, and leverage Rust’s type system for safer null handling.
