Struct IntegrityMetadata

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

An integrity metadata string as defined in W3C SRI.

Implementations

impl IntegrityMetadata

pub fn parse(s: &str) -> Result<Self, Error>

Parses an IntegrityMetadata from a string.

Example

use identity_credential::sd_jwt_vc::metadata::IntegrityMetadata;

let integrity_data = IntegrityMetadata::parse(
  "sha384-dOTZf16X8p34q2/kYyEFm0jh89uTjikhnzjeLeF0FHsEaYKb1A1cv+Lyv4Hk8vHd",
)
.unwrap();

pub fn alg(&self) -> &str

Returns the digest algorithm’s identifier string.

Example

use identity_credential::sd_jwt_vc::metadata::IntegrityMetadata;

let integrity_data: IntegrityMetadata =
  "sha384-dOTZf16X8p34q2/kYyEFm0jh89uTjikhnzjeLeF0FHsEaYKb1A1cv+Lyv4Hk8vHd"
    .parse()
    .unwrap();
assert_eq!(integrity_data.alg(), "sha384");

pub fn digest(&self) -> &str

Returns the base64 encoded digest part.

Example

use identity_credential::sd_jwt_vc::metadata::IntegrityMetadata;

let integrity_data: IntegrityMetadata =
  "sha384-dOTZf16X8p34q2/kYyEFm0jh89uTjikhnzjeLeF0FHsEaYKb1A1cv+Lyv4Hk8vHd"
    .parse()
    .unwrap();
assert_eq!(
  integrity_data.digest(),
  "dOTZf16X8p34q2/kYyEFm0jh89uTjikhnzjeLeF0FHsEaYKb1A1cv+Lyv4Hk8vHd"
);

pub fn digest_bytes(&self) -> Vec<u8>

Returns the digest’s bytes.

pub fn options(&self) -> Option<&str>

Returns the option part.

Example

use identity_credential::sd_jwt_vc::metadata::IntegrityMetadata;

let integrity_data: IntegrityMetadata =
  "sha384-dOTZf16X8p34q2/kYyEFm0jh89uTjikhnzjeLeF0FHsEaYKb1A1cv+Lyv4Hk8vHd"
    .parse()
    .unwrap();
assert!(integrity_data.options().is_none());

Trait Implementations

fn as_ref(&self) -> &str

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

impl Clone for IntegrityMetadata

fn clone(&self) -> IntegrityMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IntegrityMetadata

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IntegrityMetadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for IntegrityMetadata

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

Formats the value using the given formatter.

impl FromStr for IntegrityMetadata

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for IntegrityMetadata

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 IntegrityMetadata

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

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

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<String> for IntegrityMetadata

type Error = Error

The type returned in the event of a conversion error.

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

Performs the conversion.
