Function fibonacci_prime_cache 

pub fn fibonacci_prime_cache(n: u64) -> u64

Primes the cached function fibonacci. Example of how to use the cached attribute

// Example disabled due to missing cached dependency
use cached::proc_macro::cached;

#[cached(size = 100)]
pub fn expensive_calculation(x: u64) -> u64 {
    // Expensive computation here
    x * x
}

Example of using TTL cache for memoization

This example shows how to use the TTL cache for memoizing expensive operations.

use scirs2_core::cache::TTLSizedCache;
use std::time::Duration;

// Create a TTL cache
let mut cache = TTLSizedCache::<String, String>::new(100, 60);

// Cache a value
let key = "example_key";
let value = "example_value";
cache.insert(key.to_string(), value.to_string());

// Retrieve a value
let retrieved_value = cache.get(&key.to_string());

Compute Fibonacci numbers with memoization

This function demonstrates the use of memoization for computing Fibonacci numbers efficiently.

Example

use cached::proc_macro::cached;

#[cached(size = 100)]
pub fn fibonacci_prime_cache(n: u64) -> u64 {
    match n {
        0 => 0,
        1 => 1,
        n => fibonacci_prime_cache(n - 1) + fibonacci_prime_cache(n - 2),
    }
}

Arguments

• n - The Fibonacci number to compute

Returns

• The nth Fibonacci number

Caching

This is a cached function that uses the FIBONACCI cached static.
