Struct cargo::core::compiler::Unit

pub struct Unit { /* fields omitted */ }

All information needed to define a unit.

A unit is an object that has enough information so that cargo knows how to build it. For example, if your package has dependencies, then every dependency will be built as a library unit. If your package is a library, then it will be built as a library unit as well, or if it is a binary with main.rs, then a binary will be output. There are also separate unit types for testing and checking, amongst others.

The unit also holds information about all possible metadata about the package in pkg.

A unit needs to know extra information in addition to the type and root source file. For example, it needs to know the target architecture (OS, chip arch etc.) and it needs to know whether you want a debug or release build. There is enough information in this struct to figure all that out.

Implementations

impl Unit

pub fn buildkey(&self) -> String

Trait Implementations

impl Clone for Unit

fn clone(&self) -> Unit

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Unit

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

Formats the value using the given formatter.

impl Deref for Unit

type Target = UnitInner

The resulting type after dereferencing.

fn deref(&self) -> &UnitInner

Dereferences the value.

impl Eq for Unit

impl Hash for Unit

fn hash<H: Hasher>(&self, hasher: &mut H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl Ord for Unit

fn cmp(&self, other: &Unit) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Unit> for Unit

fn eq(&self, other: &Unit) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<Unit> for Unit

fn partial_cmp(&self, other: &Unit) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Unit) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Unit) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Unit) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Unit) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
