Struct PullAll

pub struct PullAll {
    pub variables: Vec<u32>,
    pub pull_attributes: Vec<Aid>,
}

TODO

pull_attributes: Vec<Aid>

Attributes to pull for the input entities.

Trait Implementations

impl Clone for PullAll

fn clone(&self) -> PullAll

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PullAll

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PullAll

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for PullAll

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 Implementable for PullAll

fn dependencies(&self) -> Dependencies

Returns names of any other implementable things that need to be available before implementing this one. Attributes are not mentioned explicitley as dependencies.

fn implement<'b, T, I, S>( &self, nested: &mut Iterative<'b, S, u64>, _local_arrangements: &HashMap<String, Variable<Iterative<'b, S, u64>, Vec<Value>, isize>>, context: &mut I, ) -> (Implemented<'b, S>, ShutdownHandle)

where T: Timestamp + Lattice, I: ImplContext<T>, S: Scope<Timestamp = T>,

Implements the type as a simple relation.

fn into_bindings(&self) -> Vec<Binding>

Transforms an implementable into an equivalent set of bindings that can be unified by Hector.

fn datafy(&self) -> Vec<(Eid, Aid, Value)>

@TODO

impl Ord for PullAll

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

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

fn partial_cmp(&self, other: &PullAll) -> 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 Serialize for PullAll

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
