Struct ContentHash 

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

Implementations

impl ContentHash

pub fn new(value: u32) -> Self

pub fn of<T: Hash>(value: &T) -> Self

The content hash of any Hash value, via FNV-1a. Deterministic for a given structure — the same parsed value always hashes the same — which is what makes it usable as a stable, structure-derived identifier.

Trait Implementations

impl Clone for ContentHash

fn clone(&self) -> ContentHash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ContentHash

impl Debug for ContentHash

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

Formats the value using the given formatter.

impl Display for ContentHash

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

Formats the value using the given formatter.

impl Eq for ContentHash

impl Hash for ContentHash

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 ContentHash

fn eq(&self, other: &ContentHash) -> 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 Serialize for ContentHash

Serializes as the eight-hex-digit string (its Display) — the same form that suffixes a physical index name — rather than the raw u32.

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
