Struct Arg 

pub struct Arg<T> { /* private fields */ }

Wrapper for function arguments included in cache key extraction.

This type wraps arguments that should contribute to the cache key. The inner type must implement KeyExtract.

The parameter name is used to disambiguate cache keys:

• Single inner KeyPart → key is replaced with the parameter name
• Multiple inner KeyParts → each key is prefixed with "param_name."

Implementations

impl<T> Arg<T>

pub fn new(name: &'static str, value: T) -> Self

Create a new named argument that will be included in the cache key.

pub fn value(&self) -> &T

Get a reference to the inner value.

pub fn into_value(self) -> T

Unwrap and return the inner value.

Trait Implementations

impl<T: Clone> Clone for Arg<T>

fn clone(&self) -> Arg<T>

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for Arg<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: KeyExtract> KeyExtract for Arg<T>

fn extract(&self) -> Vec<KeyPart>
