Struct Needs 

pub struct Needs {}

What a slice needs of whoever runs it.

Empty, and named. This is where this wants a GPU with 40 GB will go, and it goes nowhere until there is a queue that reads it — inventing fields now would be describing a matching policy nobody has written. What it buys empty is that the day it fills, Reach does not change shape.

A struct and not a unit so that filling it is an edit here rather than a change of kind at every construction site.

Trait Implementations

impl Clone for Needs

fn clone(&self) -> Needs

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Needs

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

Formats the value using the given formatter.

impl Default for Needs

fn default() -> Needs

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Needs

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Needs

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Needs

impl StructuralPartialEq for Needs
