Struct ObjectId 

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

16-byte truncated content-addressed identity for an ECS object.

Spec: ObjectId = Trunc128(BLAKE3("fsqlite:ecs:v1" || canonical_object_header || payload_hash)).

Implementations

impl ObjectId

pub const LEN: usize = 16

ObjectId length in bytes.

pub const DOMAIN_SEPARATOR: &'static [u8] = ECS_OBJECT_ID_DOMAIN_SEPARATOR

Domain separation prefix from the spec.

pub const fn from_bytes(bytes: [u8; 16]) -> Self

Construct from raw bytes.

pub const fn as_bytes(&self) -> &[u8; 16]

Return the raw bytes.

pub fn derive_from_canonical_bytes(canonical_bytes: &[u8]) -> Self

Derive an ObjectId from already-canonicalized bytes.

canonical_bytes must be a deterministic, versioned wire-format blob (spec: “not serde vibes”) representing the object’s header plus its payload_hash.

pub fn derive(canonical_object_header: &[u8], payload_hash: PayloadHash) -> Self

Derive an ObjectId from canonical header bytes and a payload hash.

Trait Implementations

impl AsRef<[u8]> for ObjectId

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ObjectId

fn clone(&self) -> ObjectId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ObjectId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ObjectId

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

Formats the value using the given formatter.

impl From<[u8; 16]> for ObjectId

fn from(value: [u8; 16]) -> Self

Converts to this type from the input type.

impl Hash for ObjectId

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 ObjectId

fn cmp(&self, other: &ObjectId) -> 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 ObjectId

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

fn partial_cmp(&self, other: &ObjectId) -> 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.

impl Serialize for ObjectId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ObjectId

impl Eq for ObjectId
