Struct EntropyMapBitpackedLookup 

pub struct EntropyMapBitpackedLookup { /* private fields */ }

Wrapper around entropy-map’s MapWithDictBitpacked for u32 -> u8 lookups This version uses bitpacking for even more compact storage Note: For now, we’ll use a simpler approach and just use MapWithDict with a different name TODO: Implement proper MapWithDictBitpacked support when API is clearer

Implementations

impl EntropyMapBitpackedLookup

pub fn new(entries: &[(u32, u8)]) -> (Self, u64)

Create a new bitpacked entropy map from key-value pairs Returns the map and construction time in nanoseconds

pub fn lookup(&self, key: u32) -> u8

Lookup a single value, returns 0 if key not found

pub fn lookup_batch(&self, keys: &[u32], results: &mut [u8])

Lookup multiple values at once

pub fn memory_usage(&self) -> usize

Get memory usage information
