Enum BuildPlatform

pub enum BuildPlatform {
    Target,
    Host,
}

Either the target or the host platform.

When Cargo computes the platforms it is building on, it computes two separate build graphs: one for the target platform and one for the host. This is most useful in cross-compilation situations where the target is different from the host, but the separate graphs are computed whether or not a build cross-compiles.

A cargo check can be looked at as a kind of cross-compilation as well–machine code is generated and run for the host platform but not the target platform. This is why cargo check output usually has some lines that say Compiling (for the host platform) and some that say Checking (for the target platform).

Variants

Target

The target platform.

This represents the packages and features that are included as code in the final build artifacts.

Host

The host platform.

This represents build scripts, proc macros and other code that is run on the machine doing the compiling.

Implementations

impl BuildPlatform

pub const VALUES: &'static [Self; 2] = _

A list of all possible variants of BuildPlatform.

pub fn flip(self) -> Self

Returns the build platform that’s not self.

Trait Implementations

impl Clone for BuildPlatform

fn clone(&self) -> BuildPlatform

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BuildPlatform

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

Formats the value using the given formatter.

impl Display for BuildPlatform

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

Formats the value using the given formatter.

impl Hash for BuildPlatform

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 Ord for BuildPlatform

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for BuildPlatform

fn eq(&self, other: &BuildPlatform) -> 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 PartialOrd for BuildPlatform

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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