Implementations

impl<'a> Set<'a>

pub fn dependencies(&self) -> impl ExactSizeIterator<Item = &Set<'a>>

Returns an iterator of sets that must be defined before this one.

Trait Implementations

impl<'a> Clone for Set<'a>

fn clone(&self) -> Set<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Set<'a>

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

Formats the value using the given formatter.

impl Default for Set<'_>

fn default() -> Self

Returns the “default value” for a type.

impl<'a> From<FilterSet<'a>> for Set<'a>

fn from(value: FilterSet<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<Set<'a>> for Query<'a>

fn from(value: Set<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<UnionSet<'a>> for Set<'a>

fn from(value: UnionSet<'a>) -> Self

Converts to this type from the input type.

impl Hash for Set<'_>

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<'a> Into<Cow<'a, Set<'a>>> for &'a Set<'a>

fn into(self) -> Cow<'a, Set<'a>>

Converts this type into the (usually inferred) input type.

impl<'a> Into<Cow<'a, Set<'a>>> for Set<'a>

fn into(self) -> Cow<'a, Set<'a>>

Converts this type into the (usually inferred) input type.

impl<'a> Into<Set<'a>> for FilterSetBuilder<'a>

fn into(self) -> Set<'a>

Converts this type into the (usually inferred) input type.

impl<'a> Into<Set<'a>> for FilterType

fn into(self) -> Set<'a>

Converts this type into the (usually inferred) input type.

impl<'a> Into<Set<'a>> for UnionSetBuilder<'a>

fn into(self) -> Set<'a>

Converts this type into the (usually inferred) input type.

impl PartialEq for Set<'_>

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