Struct ExcludeElement 

pub struct ExcludeElement<X: Extension = NoExt> {
    pub expr: Expr<X>,
    pub parenthesized: bool,
    pub collation: Option<ObjectName>,
    pub opclass: Option<ObjectName>,
    pub opclass_params: ThinVec<TableStorageParameter<X>>,
    pub asc: Option<bool>,
    pub nulls_first: Option<bool>,
    pub operator: ExcludeOperator,
    pub meta: Meta,
}

One <index_element> WITH <operator> element of an ExcludeConstraint (PostgreSQL ExclusionConstraintElem).

The index element is PostgreSQL’s index_elem: a key (a bare column, a bare function call, or a parenthesized (a_expr) — the parenthesized flag records which so the source form round-trips), then optional COLLATE, an operator-class name with optional reloptions, and ASC/DESC + NULLS FIRST/LAST sort modifiers — exactly the CreateIndex key grammar. The WITH <operator> names the exclusion operator.

Fields

expr: Expr<X>

Expression evaluated by this syntax.

parenthesized: bool

Whether the key was written parenthesized ((a + b)); a bare column / function call is unparenthesized. Mirrors PartitionElem::parenthesized.

collation: Option<ObjectName>

Optional collation for this syntax.

opclass: Option<ObjectName>

The operator-class name (index_elem opt_qualified_name), when written — a int4_ops, a myschema.text_ops.

opclass_params: ThinVec<TableStorageParameter<X>>

The operator-class reloptions (<param> [= <value>], ...) (index_elem reloptions), present only with an opclass; empty otherwise.

asc: Option<bool>

ASC (Some(true)) / DESC (Some(false)) sort order; None when unwritten.

nulls_first: Option<bool>

NULLS FIRST (Some(true)) / NULLS LAST (Some(false)); None when unwritten.

operator: ExcludeOperator

Operator applied by this expression.

meta: Meta

Source location and node identity.

Trait Implementations

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