Struct cargo::core::profiles::UnitFor

pub struct UnitFor { /* fields omitted */ }

Flags used in creating Units to indicate the purpose for the target, and to ensure the target’s dependencies have the correct settings.

Implementations

impl UnitFor

pub fn new_normal() -> UnitFor

A unit for a normal target/dependency (i.e., not custom build, proc macro/plugin, or test/bench).

pub fn new_build() -> UnitFor

A unit for a custom build script or its dependencies.

pub fn new_compiler() -> UnitFor

A unit for a proc macro or compiler plugin or their dependencies.

pub fn new_test(config: &Config) -> UnitFor

A unit for a test/bench target or their dependencies.

Note that config is taken here for unstable CLI features to detect whether panic=abort is supported for tests. Historical versions of rustc did not support this, but newer versions do with an unstable compiler flag.

pub fn with_for_host(self, for_host: bool) -> UnitFor

Creates a variant based on for_host setting.

When for_host is true, this clears panic_abort_ok in a sticky fashion so that all its dependencies also have panic_abort_ok=false. This’ll help ensure that once we start compiling for the host platform (build scripts, plugins, proc macros, etc) we’ll share the same build graph where everything is panic=unwind.

pub fn is_build(self) -> bool

Returns true if this unit is for a custom build script or one of its dependencies.

pub fn all_values() -> &'static [UnitFor]

All possible values, used by clean.

Trait Implementations

impl Clone for UnitFor

fn clone(&self) -> UnitFor

impl Copy for UnitFor

impl Debug for UnitFor

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

Formats the value using the given formatter.

impl Eq for UnitFor

impl Hash for UnitFor

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

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

impl Ord for UnitFor

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<UnitFor> for UnitFor

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

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

fn ne(&self, other: &UnitFor) -> bool

This method tests for !=.

impl PartialOrd<UnitFor> for UnitFor

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

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

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

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

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

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

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

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

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

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