Struct FNV1a_64 

pub struct FNV1a_64 { /* private fields */ }

Implementations

impl FNV1a_64

pub const fn new() -> Self

Creates a new instance of FNV1a_64 with the default initial state.

pub const fn with_seed(seed: u64) -> Self

Creates a new instance of FNV1a_64 from seed.

pub const fn update_const(&self) -> u64

Returns calculated hash.

impl FNV1a_64

pub const fn result_const(&mut self, data: &[u8])

Updates internal FNV1a_64 state with a given bytes block.

Trait Implementations

impl Default for FNV1a_64

fn default() -> Self

Returns the “default value” for a type.

impl HashFunction for FNV1a_64

type Output = [u8; 8]

fn update(&mut self, data: impl AsRef<[u8]>)

Updates the internal state of the HashFunction with given data.

fn write_result(&self, output: &mut Self::Output)

Writes the final result to the output passed as ref parameter.

fn result(&self) -> Self::Output

A wrapper around HashFunction::write_result that returns the hash instead of writing it to output parameter.

impl Hasher for FNV1a_64

fn finish(&self) -> u64

Returns the hash value for the values written so far.

fn write(&mut self, bytes: &[u8])

Writes some data into this Hasher.

fn write_u8(&mut self, i: u8)

Writes a single u8 into this hasher.

fn write_u16(&mut self, i: u16)

Writes a single u16 into this hasher.

fn write_u32(&mut self, i: u32)

Writes a single u32 into this hasher.

fn write_u64(&mut self, i: u64)

Writes a single u64 into this hasher.

fn write_u128(&mut self, i: u128)

Writes a single u128 into this hasher.

Writes a single i32 into this hasher.

fn write_i64(&mut self, i: i64)

Writes a single i64 into this hasher.

fn write_i128(&mut self, i: i128)

Writes a single i128 into this hasher.

fn write_isize(&mut self, i: isize)

Writes a single isize into this hasher.

fn write_length_prefix(&mut self, len: usize)

🔬This is a nightly-only experimental API. (hasher_prefixfree_extras)

Writes a length prefix into this hasher, as part of being prefix-free.

fn write_str(&mut self, s: &str)

🔬This is a nightly-only experimental API. (hasher_prefixfree_extras)

Writes a single str into this hasher.

impl PartialEq for FNV1a_64

fn eq(&self, other: &FNV1a_64) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ReprC for FNV1a_64

const CHECK: () = ()

This field is used for const checks only.
