Struct IndexStorageOptions 

pub struct IndexStorageOptions {
    pub fillfactor: Option<u32>,
    pub fastupdate: Option<bool>,
    pub gin_pending_list_limit: Option<u64>,
    pub buffering: Option<BufferingMode>,
    pub deduplicate_items: Option<bool>,
    pub pages_per_range: Option<u32>,
    pub autosummarize: Option<bool>,
    pub extra: BTreeMap<String, String>,
}

Storage options for indexes. Valid keys depend on access method; parse-time validation enforces per-AM rules.

Fields

fillfactor: Option<u32>

fillfactor — target index page density; valid range depends on access method.

fastupdate: Option<bool>

fastupdate — GIN: defer index updates via a pending list.

gin_pending_list_limit: Option<u64>

gin_pending_list_limit — GIN: max size of pending list before cleanup (bytes).

buffering: Option<BufferingMode>

buffering — GiST / SP-GiST: controls buffered build strategy.

deduplicate_items: Option<bool>

deduplicate_items — B-tree (PG 13+): enable deduplication of posting lists.

pages_per_range: Option<u32>

pages_per_range — BRIN: number of heap pages per BRIN range.

autosummarize: Option<bool>

autosummarize — BRIN: auto-summarize when pages_per_range fills.

extra: BTreeMap<String, String>

Unknown / extension-registered options. Always sorted by key (BTreeMap).

Implementations

impl IndexStorageOptions

pub fn is_empty(&self) -> bool

true iff every typed field is None and extra is empty.

Trait Implementations

impl Clone for IndexStorageOptions

fn clone(&self) -> IndexStorageOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexStorageOptions

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

Formats the value using the given formatter.

impl Default for IndexStorageOptions

fn default() -> IndexStorageOptions

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for IndexStorageOptions

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for IndexStorageOptions

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 IndexStorageOptions

fn cmp(&self, other: &IndexStorageOptions) -> 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.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for IndexStorageOptions

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

impl PartialOrd for IndexStorageOptions

fn partial_cmp(&self, other: &IndexStorageOptions) -> 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

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

impl Serialize for IndexStorageOptions

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for IndexStorageOptions
