Struct PerfectHashView 

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

Borrowed reader for a serialized ProtoCache perfect-hash index.

Implementations

impl<'a> PerfectHashView<'a>

pub fn new(data: &'a [u8]) -> Result<Self, ReadError>

Parses and bounds-checks an index from the beginning of data.

pub fn data_size(&self) -> usize

Returns the number of bytes occupied by the parsed index.

pub fn len(&self) -> usize

Returns the number of indexed keys.

pub fn is_empty(&self) -> bool

pub fn locate(&self, key: &[u8]) -> Option<usize>

Returns the candidate storage position for key.

The index stores no key bytes, so callers must compare the key stored at the returned position before treating the lookup as a match.
