Enum cargo::core::compiler::CompileKind

pub enum CompileKind {
    Host,
    Target(CompileTarget),
}

Indicator for how a unit is being compiled.

This is used primarily for organizing cross compilations vs host compilations, where cross compilations happen at the request of --target and host compilations happen for things like build scripts and procedural macros.

Variants

Host

Attached to a unit that is compiled for the "host" system or otherwise is compiled without a --target flag. This is used for procedural macros and build scripts, or if the --target flag isn't passed.

Target(CompileTarget)

Attached to a unit to be compiled for a particular target. This is used for units when the --target flag is passed.

Implementations

impl CompileKind

pub fn is_host(&self) -> bool

pub fn for_target(self, target: &Target) -> CompileKind

pub fn from_requested_targets(
    config: &Config,
    targets: &[String]
) -> CargoResult<Vec<CompileKind>>

Creates a new list of CompileKind based on the requested list of targets.

If no targets are given then this returns a single-element vector with CompileKind::Host.

Trait Implementations

impl Clone for CompileKind

fn clone(&self) -> CompileKind

Returns a copy of the value.

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

impl Eq for CompileKind

impl Hash for CompileKind

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

impl Ord for CompileKind

fn cmp(&self, other: &CompileKind) -> 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<CompileKind> for CompileKind

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

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

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

This method tests for !=.

impl PartialOrd<CompileKind> for CompileKind

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

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

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

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

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

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

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

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

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