Struct SnapshotId 

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

The digest identity of an immutable base snapshot.

Implementations

impl SnapshotId

pub const fn from_bytes(bytes: [u8; 32]) -> Self

Construct an identifier from its canonical 32 bytes.

pub const fn as_bytes(&self) -> &[u8; 32]

Return the canonical identifier bytes.

impl SnapshotId

pub fn digest_manifest(canonical_manifest: &[u8]) -> Self

Hash a canonical snapshot manifest with a VSH domain separator.

impl Eq for SnapshotId

impl FromStr for SnapshotId

type Err = ParseDigestError

The associated error which can be returned from parsing.

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

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

impl Hash for SnapshotId

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,

impl Ord for SnapshotId

fn cmp(&self, other: &SnapshotId) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for SnapshotId

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for SnapshotId

fn partial_cmp(&self, other: &SnapshotId) -> 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.
