Struct TargetSet 

pub struct TargetSet { /* private fields */ }

A set of unique Targets, ordered by target triple.

The targets are held behind an Arc, so cloning a set, and with it cloning the Toolchain which holds it, does not copy its targets.

Two toolchains which support the same targets can share a single set. As you can imagine, this happens a lot in Rust distribution land, so it’s well worth vs a regular BTreeSet ;).

Implementations

impl TargetSet

pub fn len(&self) -> usize

The amount of targets in the set.

pub fn is_empty(&self) -> bool

Returns true if the set holds no targets, and false otherwise.

pub fn contains(&self, target: &Target) -> bool

Returns true if the given target is a member of the set.

pub fn iter(&self) -> Iter<'_, Target>

Iterate over the targets of the set.

pub fn as_slice(&self) -> &[Target]

The targets of the set, as a slice ordered by target triple.

Trait Implementations

impl Clone for TargetSet

fn clone(&self) -> TargetSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TargetSet

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

Formats the value using the given formatter.

impl Default for TargetSet

fn default() -> Self

Returns the “default value” for a type.

impl Eq for TargetSet

impl From<Vec<Target>> for TargetSet

fn from(targets: Vec<Target>) -> Self

Converts to this type from the input type.

impl FromIterator<Target> for TargetSet

fn from_iter<I: IntoIterator<Item = Target>>(iter: I) -> Self

Creates a value from an iterator.

impl<'a> IntoIterator for &'a TargetSet

type Item = &'a Target

The type of the elements being iterated over.

type IntoIter = Iter<'a, Target>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter
