Struct ValueMesh

pub struct ValueMesh<T> { /* private fields */ }

A mesh of values, where each value is associated with a rank.

Invariant

The mesh is complete: ranks.len() always equals region.num_ranks(). Every rank in the region has exactly one associated value.

Implementations

impl<F: Future> ValueMesh<F>

pub async fn join(self) -> ValueMesh<F::Output>

Await all futures in the mesh, yielding a ValueMesh of their outputs.

impl<T, E> ValueMesh<Result<T, E>>

pub fn transpose(self) -> Result<ValueMesh<T>, E>

Transposes a ValueMesh<Result<T, E>> into a Result<ValueMesh<T>, E>.

Trait Implementations

impl<T> BuildFromRegion<T> for ValueMesh<T>

type Error = Error

fn build_dense(region: Region, values: Vec<T>) -> Result<Self, Self::Error>

Validates cardinality/shape and constructs a mesh.

fn build_dense_unchecked(region: Region, values: Vec<T>) -> Self

Caller guarantees correct cardinality/order; no validation.

impl<T> BuildFromRegionIndexed<T> for ValueMesh<T>

type Error = Error

fn build_indexed( region: Region, pairs: impl IntoIterator<Item = (usize, T)>, ) -> Result<Self, Self::Error>

Validates coverage and bounds, and constructs a mesh from (rank, value) pairs.

impl<T: Clone> Clone for ValueMesh<T>

fn clone(&self) -> ValueMesh<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for ValueMesh<T>

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

Formats the value using the given formatter.

impl<T: Hash> Hash for ValueMesh<T>

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<T: PartialEq> PartialEq for ValueMesh<T>

fn eq(&self, other: &ValueMesh<T>) -> 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<T: 'static> Ranked for ValueMesh<T>

type Item = T

The type of item in this view.

fn region(&self) -> &Region

The ranks contained in this view.

fn get(&self, rank: usize) -> Option<&Self::Item>

Return the item at rank

impl<T: Clone + 'static> RankedSliceable for ValueMesh<T>

fn sliced(&self, region: Region) -> Self

Construct a new Ranked containing the ranks in this view that are part of region. The caller guarantees that region.is_subset(self.region()).
