Struct NameHash 

pub struct NameHash(pub [u8; 4]);

4-byte name hash (§7.3.4.5 — “MD5(name)[0..4]”).

Stored in the MinimalTypeObject instead of the full name, to keep the payload small. In the CompleteTypeObject the full name is additionally present.

Tuple Fields

0: [u8; 4]

Implementations

impl NameHash

pub fn from_name(name: &str) -> Self

Computes the 4-byte NameHash from a member/literal name.

Spec §7.3.4.5: “the name_hash is computed as the first 4 octets of the MD5 hash of the name, interpreted as ASCII/UTF-8”.

pub fn encode_into(&self, w: &mut BufferWriter) -> Result<(), EncodeError>

Encoded as octet[4] (4 bytes, no length, no padding).

Errors

Buffer overflow.

pub fn decode_from(r: &mut BufferReader<'_>) -> Result<Self, DecodeError>

Decoder.

Errors

Buffer underflow.

Trait Implementations

impl Clone for NameHash

fn clone(&self) -> NameHash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NameHash

impl Debug for NameHash

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

Formats the value using the given formatter.

impl Default for NameHash

fn default() -> NameHash

Returns the “default value” for a type.

impl Eq for NameHash

impl Hash for NameHash

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 Ord for NameHash

fn cmp(&self, other: &NameHash) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for NameHash

fn eq(&self, other: &NameHash) -> 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 PartialOrd for NameHash

fn partial_cmp(&self, other: &NameHash) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
