Enum IndexKey 

pub enum IndexKey {
    Int(i64),
    Str(String),
    Tuple(IndexTuple),
}

A serializable index key from a Set.

Variants

Int(i64)

Str(String)

Tuple(IndexTuple)

Implementations

impl IndexKey

pub fn tuple<I, T>(iter: I) -> Self

where I: IntoIterator<Item = T>, T: Into<IndexKey>,

Build a tuple key from any iterable of convertible items. Nested tuple keys are flattened.

pub fn as_i64(&self) -> Option<i64>

pub fn as_str(&self) -> Option<&str>

pub fn as_tuple(&self) -> Option<&[IndexKey]>

fn from(t: (A, B, C)) -> Self

Converts to this type from the input type.

impl<A, B, C, D> From<(A, B, C, D)> for IndexKey

impl FromIndexKey for IndexKey

fn from_index_key(k: &IndexKey) -> Self

impl Hash for IndexKey

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,

impl<'a> Index<&IndexKey> for IndexedVar<'a>

type Output = Expr<'a>

The returned type after indexing.

fn index(&self, key: &IndexKey) -> &Self::Output

Performs the indexing (container[index]) operation.

impl PartialEq for IndexKey

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