Struct thunderdome::Index

pub struct Index { /* fields omitted */ }

Index type for Arena that has a generation attached to it.

Implementations

impl Index

pub fn to_bits(self) -> u64

Convert this Index to an equivalent u64 representation. Mostly useful for passing to code outside of Rust.

pub fn from_bits(bits: u64) -> Self

Convert back from a value generated with Index::to_bits. Don't call this with arbitrary inputs; you'll almost certainly just get invalid and/or malformed indices.

If fed an index which was not generated by thunderdome or even just run Index::from_bits(0), this function may panic!

pub fn slot(self) -> u32

Convert this Index into a slot, discarding its generation. Slots describe a location in an Arena and are reused when entries are removed.

Trait Implementations

impl Clone for Index

fn clone(&self) -> Index

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Index

impl Debug for Index

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

Formats the value using the given formatter.

impl Eq for Index

impl Hash for Index

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, 

Feeds a slice of this type into the given Hasher.

impl<T> Index<Index> for Arena<T>

type Output = T

The returned type after indexing.

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

Performs the indexing (container[index]) operation.

impl<T> IndexMut<Index> for Arena<T>

fn index_mut(&mut self, index: Index) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl Ord for Index

fn cmp(&self, other: &Index) -> Ordering

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Index> for Index

fn eq(&self, other: &Index) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Index) -> bool

This method tests for !=.

impl PartialOrd<Index> for Index

fn partial_cmp(&self, other: &Index) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Index) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Index) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Index) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Index) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
