Struct CacheInfo 

pub struct CacheInfo {
    pub level: CacheLevel,
    pub cache_type: CacheType,
    pub size_bytes: u64,
    pub line_size_bytes: usize,
}

Represents detailed information about a specific CPU cache.

This structure provides insights into the cache’s characteristics, such as its level in the memory hierarchy, its designated type (e.g., for data or instructions), its total size, and the size of its cache lines. This information is crucial for performance-sensitive applications that need to optimize memory access patterns.

Fields

level: CacheLevel

The hierarchical level of the cache (e.g., L1, L2, L3).

Lower levels (like L1) are smaller, faster, and closer to the CPU core, while higher levels (like L3) are larger, slower, and typically shared among multiple cores.

cache_type: CacheType

The designated purpose of the cache.

This can be:

• Data: Cache dedicated to storing data.
• Instruction: Cache dedicated to storing executable instructions.
• Unified: Cache used for both data and instructions.

size_bytes: u64

The total size of the cache, expressed in bytes.

For example, a value of 32768 would represent a 32KB cache.

line_size_bytes: usize

The size of a single cache line (also known as a cache block), in bytes.

Data is transferred between the cache and main memory in units of cache lines. Knowing the line size can be important for optimizing data layout to avoid issues like false sharing in multi-threaded applications.
