Enum BuildTargetId

#[non_exhaustive]
pub enum BuildTargetId<'g> {
    Library,
    BuildScript,
    Binary(&'g str),
    Example(&'g str),
    Test(&'g str),
    Benchmark(&'g str),
}

An identifier for a build target within a package.

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.

Library

A library target.

There may be at most one of these in a package.

Defined by the [lib] section in Cargo.toml.

BuildScript

A build script.

There may be at most one of these in a package.

Defined by the build attribute in Cargo.toml. For more about build scripts, see Build Scripts in the Cargo reference.

Binary(&'g str)

A binary target with its name.

Defined by the [[bin]] section in Cargo.toml.

Example(&'g str)

An example target with its name.

Examples are typically binary, but may be libraries or even both.

Defined by the [[example]] section in Cargo.toml.

Test(&'g str)

A test target with its name.

Tests are always binary targets.

Defined by the [[test]] section in Cargo.toml.

Benchmark(&'g str)

A benchmark target with its name.

Benchmarks are always binary targets.

Defined by the [[bench]] section in Cargo.toml.

Implementations

impl<'g> BuildTargetId<'g>

pub fn name(&self) -> Option<&'g str>

Returns the name embedded in this identifier, or None if this is a library target.

To get the name of the library target, use BuildTarget::name.

Trait Implementations

impl<'g> Clone for BuildTargetId<'g>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'g> Debug for BuildTargetId<'g>

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

Formats the value using the given formatter.

impl<'g> Hash for BuildTargetId<'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 BuildTargetId<'g>

fn cmp(&self, other: &BuildTargetId<'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 BuildTargetId<'g>

fn eq(&self, other: &BuildTargetId<'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 BuildTargetId<'g>

fn partial_cmp(&self, other: &BuildTargetId<'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.
