Struct ComponentSet 

pub struct ComponentSet { /* private fields */ }

A set of unique Components, ordered by name.

The components are held behind an Arc, so cloning a set, and with it cloning the Toolchain which holds it, does not copy its components. Two toolchains which ship the same components can share a single set.

Implementations

impl ComponentSet

pub fn len(&self) -> usize

The amount of components in the set.

pub fn is_empty(&self) -> bool

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

pub fn contains(&self, component: &Component) -> bool

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

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

Iterate over the components of the set.

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

The components of the set, as a slice ordered by name.

Trait Implementations

impl Clone for ComponentSet

fn clone(&self) -> ComponentSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ComponentSet

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

Formats the value using the given formatter.

impl Default for ComponentSet

fn default() -> Self

Returns the “default value” for a type.

impl Eq for ComponentSet

impl From<Vec<Component>> for ComponentSet

fn from(components: Vec<Component>) -> Self

Converts to this type from the input type.

impl FromIterator<Component> for ComponentSet

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

impl<'a> IntoIterator for &'a ComponentSet

type Item = &'a Component

The type of the elements being iterated over.

type IntoIter = Iter<'a, Component>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter
