Enum Space 

#[non_exhaustive]
#[repr(u8)]
pub enum Space {
    Inline = 0,
    Arena = 1,
    Log = 2,
    Hash = 3,
    Set = 4,
    ZSet = 5,
    List = 6,

}

Which world an Addr offset points into.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Inline = 0

The value is the 52 bits. Small integers and short strings live entirely inside the index entry and cost zero dereferences. This is what Redis calls int encoding and part of what it calls embstr.

Arena = 1

A byte offset into the shard’s arena segments (05 section 3).

Log = 2

A byte offset into the shard’s log region (06 section 2).

Hash = 3

A hash, as an owner local element table.

Set = 4

A set, as an owner local element table or a dense member vector.

ZSet = 5

A sorted set, as a counted B+ tree.

List = 6

A list, as a ring deque.

Stream = 7

A stream, as a radix log.

Doc = 8

A document, with its path indexes.

Vector = 9

A vector partition set.

Graph = 10

Graph adjacency.

Implementations

impl Space

pub const ALL: &'static [Space]

Every space in numeric order.

pub const fn from_bits(bits: u8) -> Option<Space>

The space for a raw 4 bit value, or None if nothing uses it yet.

pub const fn name(self) -> &'static str

The name that appears in OBJECT ENCODING style output and in errors.

Trait Implementations

impl Clone for Space

fn clone(&self) -> Space

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Space

impl Debug for Space

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

Formats the value using the given formatter.

impl Eq for Space

impl Hash for Space

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 Ord for Space

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

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

Restrict a value to a certain range.

impl PartialEq for Space

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Space

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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