Implementations

impl BinarySet

pub fn new<P>(path: P, allocation_lot: u32) -> BinarySet

where P: AsRef<Path>,

Opens the file and creates the BinarySet. /// # Arguments

• path - Path of file to save data
• allocation_lot - Extends the specified size when the file size becomes insufficient due to data addition. If you expect to add a lot of data, specifying a larger size will improve performance.

pub fn bytes(&self, row: NonZeroU32) -> Option<&'static [u8]>

Returns the value of the specified row. Returns None if the row does not exist.

pub fn row(&self, content: &[u8]) -> Option<NonZeroU32>

Search for a sequence of bytes.

pub fn row_or_insert(&mut self, content: &[u8]) -> NonZeroU32

Finds a sequence of bytes, inserts it if it doesn’t exist, and returns a row.
