Struct MacVendorCache

pub struct MacVendorCache { /* private fields */ }

A thread-safe cache for storing and retrieving MAC addresses and their associated vendor names.

The MacVendorCache struct is designed to store mappings between MAC addresses and vendor names in a thread-safe manner using an Arc<Mutex<HashMap<MacAddress, Vendor>>>. This ensures that the cache can be accessed and modified safely across multiple threads.

Trait Implementations

impl Clone for MacVendorCache

fn clone(&self) -> MacVendorCache

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl IMacVendorCache for MacVendorCache

fn new() -> Self

Creates a new instance of MacVendorCache.

The cache is initialized as an empty HashMap protected by a Mutex to allow safe concurrent access.

Returns

A new, empty MacVendorCache.

fn add(&self, mac_addr: String, vendor_name: String)

Adds a new MAC address and its associated vendor name to the cache.

If the MAC address already exists in the cache, its associated vendor name will be updated.

Arguments

• mac_addr - The MAC address to be added to the cache.
• vendor_name - The name of the vendor associated with the MAC address.

fn contains(&self, mac_addr: &String) -> bool

Checks if a given MAC address exists in the cache.

Arguments

• mac_addr - The MAC address to check in the cache.

Returns

true if the MAC address is found in the cache, false otherwise.

fn get(&self, mac_addr: &String) -> String

Retrieves the vendor name associated with a given MAC address.

If the MAC address is not found in the cache, the function returns "Unknown".

Arguments

• mac_addr - The MAC address whose associated vendor name is to be retrieved.

Returns

The vendor name associated with the MAC address, or "Unknown" if the MAC address is not found in the cache.

fn length(&self) -> usize

Returns the number of entries in the cache.

This method returns the total count of MAC address to vendor name mappings currently stored in the cache.

Returns

The number of entries in the cache.
