Struct LocalNameHash 

pub struct LocalNameHash(/* private fields */);

Available on crate feature html only.

A 64-bit hash of an ASCII-lowercased tag name.

0 is reserved to mean “no / empty name”. The hash is FNV-1a over the lowercased bytes; the known-tag constants below are verified to be collision-free by a test, which is all the dispatch paths rely on.

Implementations

impl LocalNameHash

pub const NONE: Self

The reserved “no name” hash.

pub fn of(name: &[u8]) -> Self

Hashes a tag name (ASCII-lowercasing as it goes). Returns Self::NONE for an empty name.

pub const fn from_static(name: &'static [u8]) -> Self

const constructor for known-tag constants from a static lowercase byte string.

pub const fn is_none(self) -> bool

Whether this is the reserved “no name” hash.

Trait Implementations

impl Clone for LocalNameHash

fn clone(&self) -> LocalNameHash

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for LocalNameHash

impl Debug for LocalNameHash

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LocalNameHash

fn default() -> LocalNameHash

Returns the “default value” for a type.

impl Eq for LocalNameHash

impl Hash for LocalNameHash

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for LocalNameHash

fn eq(&self, other: &LocalNameHash) -> 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.
