Struct SideEffects 

pub struct SideEffects { /* private fields */ }

An unordered set of SideEffect tags attached to a tool.

Backed by HashSet; insertion order is not preserved. Use SideEffects::iter to read out the contents.

Implementations

impl SideEffects

pub fn new() -> Self

Construct an empty set.

pub fn insert(&mut self, effect: SideEffect) -> bool

Insert a tag. Returns true if the tag was newly added.

pub fn remove(&mut self, effect: SideEffect) -> bool

Remove a tag. Returns true if the tag was present.

pub fn contains(&self, effect: SideEffect) -> bool

Returns true iff the set contains effect.

pub fn iter(&self) -> impl Iterator<Item = &SideEffect>

Iterate over the tags in arbitrary order.

pub fn len(&self) -> usize

Number of tags in the set.

pub fn is_empty(&self) -> bool

true iff the set is empty.

Trait Implementations

impl Clone for SideEffects

fn clone(&self) -> SideEffects

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SideEffects

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

Formats the value using the given formatter.

impl Default for SideEffects

fn default() -> SideEffects

Returns the “default value” for a type.

impl FromIterator<SideEffect> for SideEffects

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

Creates a value from an iterator.

impl PartialEq for SideEffects

fn eq(&self, other: &SideEffects) -> 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.
