Struct PartitionHandle 

pub struct PartitionHandle<H>
where
    H: HostTypes,
{ /* private fields */ }

Content-addressed identity token for a partition. Carries only a fingerprint; partition data is recovered by pairing the handle with a PartitionResolver via resolve_with. Handles compare and hash by fingerprint, so they can serve as keys in content-addressed indices without resolver access.

Implementations

impl<H> PartitionHandle<H>

where H: HostTypes,

pub const fn from_fingerprint( fingerprint: ContentFingerprint, ) -> PartitionHandle<H>

Construct a handle from a content fingerprint.

pub const fn fingerprint(&self) -> ContentFingerprint

Return the content fingerprint this handle references.

pub fn resolve_with<R>(&self, resolver: &R) -> Option<PartitionRecord<H>>

where R: PartitionResolver<H>,

Resolve this handle against a consumer-supplied resolver. Returns None if the resolver has no record for this fingerprint.

Trait Implementations

impl<H> Clone for PartitionHandle<H>

where H: HostTypes,

fn clone(&self) -> PartitionHandle<H>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<H> Debug for PartitionHandle<H>

where H: Debug + HostTypes,

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

Formats the value using the given formatter.

impl<H> Hash for PartitionHandle<H>

where H: HostTypes,

fn hash<S>(&self, state: &mut S)

where S: Hasher,

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<H> PartialEq for PartitionHandle<H>

where H: HostTypes,

fn eq(&self, other: &PartitionHandle<H>) -> 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<H> Copy for PartitionHandle<H>

where H: HostTypes,

impl<H> Eq for PartitionHandle<H>

where H: HostTypes,
