Struct BytecodeShaderCache 

pub struct BytecodeShaderCache {
    pub cache: HashMap<String, Vec<u8>>,
    pub max_size: usize,
    /* private fields */
}

Cache for compiled shader bytecode (mock compiled blobs).

Supports a maximum total byte budget; when the budget is exceeded, evict_oldest removes the oldest-inserted entry.

Fields

cache: HashMap<String, Vec<u8>>

Map from shader name to compiled bytecode.

max_size: usize

Maximum total bytes allowed.

Implementations

impl BytecodeShaderCache

pub fn new(max_size: usize) -> Self

Create a new cache with the given byte budget.

pub fn insert(&mut self, name: &str, bytecode: Vec<u8>)

Insert (or replace) a shader’s compiled bytecode.

If the total size would exceed max_size, evict_oldest is called before inserting.

pub fn get(&self, name: &str) -> Option<&Vec<u8>>

Retrieve compiled bytecode by shader name.

pub fn evict_oldest(&mut self)

Evict the oldest cached entry. No-op if cache is empty.

pub fn total_bytes(&self) -> usize

Total bytes currently stored across all cached entries.

pub fn len(&self) -> usize

Number of cached entries.

pub fn is_empty(&self) -> bool

True if the cache is empty.

Trait Implementations

impl Debug for BytecodeShaderCache

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

Formats the value using the given formatter.
