Struct StateIntegrity 

pub struct StateIntegrity {
    pub algorithm: String,
    pub digest: String,
}

Content hash of a persisted resource, used for corruption detection.

Fields

algorithm: String

Hash algorithm identifier — sha-256 in Phase A.

digest: String

Lowercase hex digest over the canonical JSON of the resource.

Implementations

impl StateIntegrity

pub fn sha256_of<T: Serialize>(value: &T) -> Result<Self, IntegrityError>

Compute the SHA-256 integrity hash over value’s canonical JSON.

pub fn verify<T: Serialize>(&self, value: &T) -> Result<bool, IntegrityError>

Recompute the hash over value and report whether it matches self.

Errors if self.algorithm is not one this build can recompute, so a caller never silently treats an unknown algorithm as a match.

Trait Implementations

impl Clone for StateIntegrity

fn clone(&self) -> StateIntegrity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StateIntegrity

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StateIntegrity

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for StateIntegrity

impl PartialEq for StateIntegrity

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
