Struct Sha256Digest 

pub struct Sha256Digest(/* private fields */);

sha256: and 64 lowercase hex digits: the one form every hash a provenance entry records takes, and nothing else — built by hashing, or read and refused when it is not one.

Implementations

impl Sha256Digest

pub fn of(bytes: &[u8]) -> Self

The digest of bytes.

pub fn parse(text: impl Into<String>) -> Result<Self, String>

The digest text spells.

Errors

Why text is not sha256: and 64 lowercase hex digits.

pub fn as_str(&self) -> &str

The digest as it is spelled.

Trait Implementations

impl Clone for Sha256Digest

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sha256Digest

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Sha256Digest

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Sha256Digest

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

Formats the value using the given formatter.

impl Eq for Sha256Digest

impl From<Sha256Digest> for String

fn from(digest: Sha256Digest) -> Self

Converts to this type from the input type.

impl Hash for Sha256Digest

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 Sha256Digest

Written by hand rather than derived, so the schema states the form a digest must take and both SDKs’ models refuse any other — a derive would describe the String it is read from.

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

The name of the generated JSON Schema.

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

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

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

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

impl PartialEq for Sha256Digest

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for Sha256Digest

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Sha256Digest

impl TryFrom<String> for Sha256Digest

type Error = String

The type returned in the event of a conversion error.

fn try_from(text: String) -> Result<Self, Self::Error>

Performs the conversion.
