Struct StateRef 

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

Immutable reference to a state (content hash).

This is the core abstraction for content-addressed storage. Two identical states will have the same StateRef.

Implementation

Currently uses BLAKE3 hash for fast, secure hashing. The hash is stored as a hex string for JSON compatibility.

Implementations

impl StateRef

pub fn from_content(content: &str) -> Self

Create a new StateRef from content.

Uses a hash of the content for addressing. Note: Currently uses std hash; production should use blake3 or sha256.

pub fn from_hash(hash: String) -> Self

Create a StateRef from an existing hash string.

Use this when deserializing from storage.

pub fn hash(&self) -> &str

Get the hash string.

pub fn short(&self) -> &str

Get a short prefix for display (first 8 chars).

pub fn is_empty(&self) -> bool

Check if this is an empty/null reference.

Trait Implementations

impl Clone for StateRef

fn clone(&self) -> StateRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StateRef

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

Formats the value using the given formatter.

impl Default for StateRef

fn default() -> StateRef

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StateRef

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for StateRef

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

Formats the value using the given formatter.

impl Hash for StateRef

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 StateRef

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
