Expand description

Implementations of SeedSize represent seed size in fingerprinting-based minimal perfect hashing with group optimization.

Required Associated Types§

Source

type VecElement: Copy + Send + Sync + GetSize

Required Methods§

Source

fn new_seed_vec( &self, seed: u16, number_of_seeds: usize, ) -> Box<[Self::VecElement]>

Source

fn get_seed(&self, vec: &[Self::VecElement], index: usize) -> u16

Source

fn set_seed(&self, vec: &mut [Self::VecElement], index: usize, seed: u16)

Source

fn write_seed_vec( &self, output: &mut dyn Write, seeds: &[Self::VecElement], ) -> Result<(), Error>

Source

fn read_seed_vec( input: &mut dyn Read, number_of_seeds: usize, ) -> Result<(Self, Box<[Self::VecElement]>), Error>

Provided Methods§

Source

fn validate(&self) -> Result<Self, &'static str>

Source

fn new_zeroed_seed_vec(&self, number_of_seeds: usize) -> Box<[Self::VecElement]>

Source

fn init_seed(&self, vec: &mut [Self::VecElement], index: usize, seed: u16)

Source

fn concatenate_seed_vecs( &self, level_sizes: &[u64], group_seeds: Vec<Box<[Self::VecElement]>>, ) -> Box<[Self::VecElement]>

Source

fn write(&self, output: &mut dyn Write) -> Result<(), Error>

Writes self to output.

Source

fn read(input: &mut dyn Read) -> Result<Self, Error>

Reads Self from input.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
