Struct DirectoryDigest 

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

The digest identity of one observed directory listing.

Implementations

impl DirectoryDigest

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 DirectoryDigest

pub fn digest_canonical(canonical_listing: &[u8]) -> Self

Hash a canonical directory-listing encoding with a VSH domain separator.

pub fn digest_entries<'a>( entries: impl IntoIterator<Item = (&'a VPath, NodeState)>, ) -> Self

Hash path-ordered direct children using VSH’s canonical listing encoding.

Callers must provide entries in canonical VPath order. Keeping this codec in the shared type crate ensures snapshot capture, virtual reads, and trusted host revalidation cannot silently diverge.

impl FromStr for DirectoryDigest

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 DirectoryDigest

impl Ord for DirectoryDigest

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

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for DirectoryDigest

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