Struct SHashSet 

pub struct SHashSet<T: StableType + AsFixedSizeBytes + Hash + Eq> { /* private fields */ }

Hashmap-based hashset

This is just a wrapper around SHashMap<T, ()>, read it’s documentation to get info on the internals.

Trait Implementations

impl<T: StableType + AsFixedSizeBytes + Hash + Eq> AsFixedSizeBytes for SHashSet<T>

const SIZE: usize = 24usize

Size of self when encoded

type Buf = <SHashMap<T, ()> as AsFixedSizeBytes>::Buf

Buffer that is used to encode this value into

fn as_fixed_size_bytes(&self, buf: &mut [u8])

Encodes itself into a slice of bytes.

fn from_fixed_size_bytes(arr: &[u8]) -> Self

Decodes itself from a slice of bytes.

fn as_new_fixed_size_bytes(&self) -> Self::Buf

Encodes itself into a new Self::Buf of size == Self::SIZE

impl<T: StableType + AsFixedSizeBytes + Hash + Eq + Debug> Debug for SHashSet<T>

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

Formats the value using the given formatter.

impl<T: StableType + AsFixedSizeBytes + Hash + Eq> Default for SHashSet<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: StableType + AsFixedSizeBytes + Hash + Eq> StableType for SHashSet<T>

unsafe fn stable_drop_flag_off(&mut self)

Sets stable drop flag to off position, if it is applicable

unsafe fn stable_drop_flag_on(&mut self)

Should set stable drop flag to on position, if it is applicable

fn should_stable_drop(&self) -> bool

Should return the value of the stable drop flag

unsafe fn stable_drop(&mut self)

Performs stable drop, releasing all underlying stable memory of this data structure
