Implementations

impl<D: Digest> Request<D>

pub fn predicate(&self) -> impl Fn(&Self) -> bool + Send + 'static

The predicate to use when pruning subjects related to this subject.

Specifically, any subjects unrelated will be left unmodified. Any related subjects will be pruned if they are “less than or equal to” this subject.

Trait Implementations

impl<D: Clone + Digest> Clone for Request<D>

fn clone(&self) -> Request<D>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<D: Digest> Debug for Request<D>

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

Formats the value using the given formatter.

impl<D: Digest> Display for Request<D>

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

Formats the value using the given formatter.

impl<D: Digest> EncodeSize for Request<D>

fn encode_size(&self) -> usize

Returns the encoded size of this value (in bytes).

impl<D: Digest> Hash for Request<D>

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<D: Digest> Ord for Request<D>

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<D: Digest> PartialEq for Request<D>

fn eq(&self, other: &Self) -> 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<D: Digest> PartialOrd for Request<D>

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.

impl<D: Digest> Read for Request<D>

type Cfg = ()

The Cfg type parameter allows passing configuration during the read process. This is crucial for safely decoding untrusted data, for example, by providing size limits for collections or strings.

fn read_cfg(buf: &mut impl Buf, _: &()) -> Result<Self, CodecError>

Reads a value from the buffer using the provided configuration cfg.

impl<D: Digest> Write for Request<D>

fn write(&self, buf: &mut impl BufMut)

Writes the binary representation of self to the provided buffer buf.

impl<D: Digest> Eq for Request<D>

impl<D: Digest> Span for Request<D>
