Struct ContentKey 

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

Content-addressed identity for an EvalRequest.

A ContentKey wraps a small Datum that records the content id of the canonical request datum. The canonical request includes the expression, required capabilities sorted lexicographically, consistency, mode, answer limit, stream buffer, stream flag, and trace flag.

Excluded fields are deliberate: deadline is a scheduling bound, not part of the requested work, and result_shape is currently a process-local runtime value rather than stable content-addressed data.

Implementations

impl ContentKey

pub fn from_request(request: &EvalRequest) -> Self

Derives a deterministic content key from the stable fields of request.

pub fn datum(&self) -> &Datum

Returns the datum representation of this key.

pub fn into_datum(self) -> Datum

Consumes this key and returns its datum representation.

Trait Implementations

impl Clone for ContentKey

fn clone(&self) -> ContentKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContentKey

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

Formats the value using the given formatter.

impl Eq for ContentKey

impl Hash for ContentKey

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 ContentKey

fn cmp(&self, other: &Self) -> 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 ContentKey

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

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