Struct ContentDigest 

pub struct ContentDigest(pub String);

A BLAKE3 content digest for idempotent deduplication.

The inner value is a 64-character hex string representing the BLAKE3 hash.

Tuple Fields

0: String

Implementations

impl ContentDigest

pub fn compute(data: &[u8]) -> Self

Compute a BLAKE3 digest from raw bytes.

pub fn compute_str(data: &str) -> Self

Compute a BLAKE3 digest from a UTF-8 string.

pub fn compute_json<T: Serialize>(value: &T) -> Result<Self, DigestError>

Compute a digest from a JSON-serializable value using canonical serialization.

Canonical serialization means:

• JSON object key ordering is normalized recursively.
• serde_json::to_string() (compact, no trailing whitespace).

For structured data with guaranteed field order (structs with named fields), serde_json produces deterministic output by default.

pub fn hex(&self) -> &str

Get the hex representation.

pub fn from_hex(hex: impl Into<String>) -> Result<Self, DigestError>

Create from a pre-computed hex string.

Validates that the string is exactly 64 hex characters.

pub fn from_hex_unchecked(hex: impl Into<String>) -> Self

Create from a pre-computed hex string without validation.

Use only when the digest is known to be valid (e.g. loaded from DB).

Trait Implementations

impl Clone for ContentDigest

fn clone(&self) -> ContentDigest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContentDigest

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ContentDigest

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ContentDigest

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

Formats the value using the given formatter.

impl Hash for ContentDigest

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 JsonSchema for ContentDigest

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

impl Ord for ContentDigest

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

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

fn partial_cmp(&self, other: &ContentDigest) -> 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 ContentDigest

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ContentDigest
