Struct PayloadHash 

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

Canonical 32-byte hash of an ECS object’s payload.

The spec refers to this as payload_hash in: ObjectId = Trunc128(BLAKE3("fsqlite:ecs:v1" || canonical_object_header || payload_hash)).

Implementations

impl PayloadHash

pub const fn from_bytes(bytes: [u8; 32]) -> Self

Construct from raw bytes.

pub const fn as_bytes(&self) -> &[u8; 32]

Return the hash bytes.

pub fn blake3(payload: &[u8]) -> Self

Hash a payload using BLAKE3-256.

Trait Implementations

impl Clone for PayloadHash

fn clone(&self) -> PayloadHash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PayloadHash

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PayloadHash

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for PayloadHash

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 PayloadHash

fn eq(&self, other: &PayloadHash) -> 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 PayloadHash

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
