Struct CreateIndex 

pub struct CreateIndex<X: Extension = NoExt> {
    pub unique: bool,
    pub concurrently: bool,
    pub if_not_exists: bool,
    pub name: Option<Ident>,
    pub table: ObjectName,
    pub using: Option<Ident>,
    pub columns: ThinVec<IndexColumn<X>>,
    pub with_params: ThinVec<TableStorageParameter<X>>,
    pub predicate: Option<Box<Expr<X>>>,
    pub meta: Meta,
}

CREATE [UNIQUE] INDEX [CONCURRENTLY] [IF NOT EXISTS] [<name>] ON <table> [USING <method>] (<column> [, ...]) [WHERE <predicate>].

UNIQUE is portable; CONCURRENTLY, the USING <method> access-method clause, and the trailing WHERE partial-index predicate are PostgreSQL extensions gated by schema_change_syntax.index_extensions dialect data. The index name is optional — PostgreSQL derives one from the table and columns when it is omitted (CREATE INDEX ON t (a)). COLLATE / operator-class / INCLUDE column decorations are a deliberate follow-up.

Fields

unique: bool

Whether the unique form was present in the source.

concurrently: bool

Whether the concurrently form was present in the source.

if_not_exists: bool

Whether the if not exists form was present in the source.

name: Option<Ident>

Name referenced by this syntax.

table: ObjectName

Table referenced by this syntax.

using: Option<Ident>

Optional using for this syntax.

columns: ThinVec<IndexColumn<X>>

Columns in source order.

with_params: ThinVec<TableStorageParameter<X>>

WITH (<name> = <value>, …) index storage parameters.

predicate: Option<Box<Expr<X>>>

Predicate that controls this clause.

meta: Meta

Source location and node identity.

Trait Implementations

impl<X: Clone + Extension> Clone for CreateIndex<X>

fn clone(&self) -> CreateIndex<X>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<X: Debug + Extension> Debug for CreateIndex<X>

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

Formats the value using the given formatter.

impl<'de, X> Deserialize<'de> for CreateIndex<X>

where X: Deserialize<'de> + Extension,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<X: Eq + Extension> Eq for CreateIndex<X>

impl<X: Hash + Extension> Hash for CreateIndex<X>

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,

fn operand_binding_power(&self) -> Option<BindingPower>

The binding power this node contributes when it appears as an operand, or None (the default) for a self-delimiting node — an atom, call, or constructor — that never needs parentheses.
