Enum BuildTargetKind

#[non_exhaustive]
pub enum BuildTargetKind<'g> {
    LibraryOrExample(&'g [String]),
    ProcMacro,
    Binary,
}

The type of build target (library or binary).

Obtained through BuildTarget::kind.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

LibraryOrExample(&'g [String])

This build target is a library or example, with the specified crate types.

The crate types are sorted and unique, and can therefore be treated like a set.

Note that examples are typically binaries, but they may be libraries as well. Binary examples will have the crate type "bin".

For more about crate types, see The crate-type field in the Cargo reference.

ProcMacro

This build target is a procedural macro.

This may only be returned for BuildTargetId::Library. This is expressed in a Cargo.toml file as:

[lib]
proc-macro = true

For more about procedural macros, see Procedural Macros in the Rust reference.

Binary

This build target is a binary target.

This kind is returned for build script, binary, test, and benchmark targets.

Trait Implementations

impl<'g> Clone for BuildTargetKind<'g>

fn clone(&self) -> BuildTargetKind<'g>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'g> Debug for BuildTargetKind<'g>

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

Formats the value using the given formatter.

impl<'g> Hash for BuildTargetKind<'g>

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<'g> Ord for BuildTargetKind<'g>

fn cmp(&self, other: &BuildTargetKind<'g>) -> 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<'g> PartialEq for BuildTargetKind<'g>

fn eq(&self, other: &BuildTargetKind<'g>) -> 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<'g> PartialOrd for BuildTargetKind<'g>

fn partial_cmp(&self, other: &BuildTargetKind<'g>) -> 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.
