Struct MapView 

pub struct MapView<'a> { /* private fields */ }

A zero-copy view over an encoded ProtoCache map and its perfect-hash index.

Implementations

impl<'a> MapView<'a>

pub fn new(words: &'a [u32]) -> Option<Self>

Parses an encoded map and validates its structural header.

pub fn detect_len(words: &'a [u32]) -> Option<usize>

Detects the complete encoded map length, including keys and values.

pub fn detect(words: &'a [u32]) -> Option<&'a [u32]>

Returns the exact encoded slice occupied by a valid map.

pub fn len(self) -> usize

Returns the number of key/value pairs.

pub fn is_empty(self) -> bool

pub fn pair(self, index: usize) -> Option<PairView<'a>>

Returns the raw pair stored at perfect-hash position index.

pub fn expect_pair(self, index: usize) -> PairView<'a>

pub fn iter(self) -> MapIter<'a>

pub fn find_bytes(self, key: &[u8]) -> Option<PairView<'a>>

Looks up an arbitrary byte-string key.

pub fn find_str(self, key: &str) -> Option<PairView<'a>>

Looks up a UTF-8 key by its encoded bytes.

pub fn find_scalar<K: MapKey + Scalar + PartialEq>( self, key: K, ) -> Option<PairView<'a>>

Looks up a scalar key using its canonical little-endian bytes.
