Enum cargo_lock::package::Checksum

pub enum Checksum {
    Sha256([u8; 32]),
}

Cryptographic checksum (SHA-256) for a package

Variants

Sha256([u8; 32])

SHA-256 digest of a package

Implementations

impl Checksum

pub fn is_sha256(&self) -> bool

Is this checksum SHA-256?

pub fn as_sha256(&self) -> Option<[u8; 32]>

If this is a SHA-256 checksum, get the raw bytes

Trait Implementations

impl Clone for Checksum

fn clone(&self) -> Checksum

Returns a copy of the value.

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

Performs copy-assignment from source.

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Checksum

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for Checksum

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

Formats the value using the given formatter.

impl From<[u8; 32]> for Checksum

fn from(bytes: [u8; 32]) -> Checksum

Converts to this type from the input type.

impl FromStr for Checksum

type Err = Error

The associated error which can be returned from parsing.

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

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

impl Hash for Checksum

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 LowerHex for Checksum

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

Formats the value using the given formatter.

impl Ord for Checksum

fn cmp(&self, other: &Checksum) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Checksum> for Checksum

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<Checksum> for Checksum

fn partial_cmp(&self, other: &Checksum) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Checksum

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl TryFrom<&MetadataValue> for Checksum

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: &MetadataValue) -> Result<Checksum>

Performs the conversion.

impl UpperHex for Checksum

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