Struct Rank

pub struct Rank(pub Option<usize>);

Data type used to communicate ranks. Implements Bind and Unbind; the comm actor replaces instances with the delivered rank.

Tuple Fields

0: Option<usize>

Implementations

impl Rank

pub fn new(rank: usize) -> Self

Create a new rank with the provided value.

pub fn unwrap(&self) -> usize

Unwrap the rank; panics if not set.

Trait Implementations

impl Bind for Rank

fn bind(&mut self, bindings: &mut Bindings) -> Result<()>

Remove parameters from bindings, and use them to update itself.

impl Clone for Rank

fn clone(&self) -> Rank

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rank

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

Formats the value using the given formatter.

impl Default for Rank

fn default() -> Rank

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Rank

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Named for Rank

fn typename() -> &'static str

The globally unique type name for the type. This should typically be the fully qualified Rust name of the type.

fn typehash() -> u64

A globally unique hash for this type. TODO: actually enforce perfect hashing

fn typeid() -> TypeId

The TypeId for this type. TypeIds are unique only within a binary, and should not be used for global identification.

fn port() -> u64

The globally unique port for this type. Typed ports are in the range of 1<<63..1<<64-1.

fn arm(&self) -> Option<&'static str>

If the named type is an enum, this returns the name of the arm of the value self.

unsafe fn arm_unchecked(self_: *const ()) -> Option<&'static str>

An unsafe version of ‘arm’, accepting a pointer to the value, for use in type-erased settings.

impl PartialEq for Rank

fn eq(&self, other: &Rank) -> 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 Serialize for Rank

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Unbind for Rank

fn unbind(&self, bindings: &mut Bindings) -> Result<()>

Extract parameters from itself and store them in bindings.

impl Eq for Rank
