Struct DropStatement 

pub struct DropStatement {
    pub object_kind: DropObjectKind,
    pub if_exists: bool,
    pub names: ThinVec<ObjectName>,
    pub behavior: Option<DropBehavior>,
    pub meta: Meta,
}

DROP {TABLE | VIEW | INDEX | SCHEMA} [IF EXISTS] <name> [, ...] [CASCADE | RESTRICT].

Non-generic: a drop names objects and a behaviour only — it carries no expressions or extension nodes — so it parallels the other leaf statement payloads (super::TransactionStatement, super::SessionStatement). The IF EXISTS prefix and the CASCADE/RESTRICT drop behaviour are each gated by schema_change_syntax dialect data. Materialized-view and concurrent-index drop surfaces are not modelled here.

Fields

object_kind: DropObjectKind

Which object kind is dropped (TABLE/VIEW/…); see DropObjectKind.

if_exists: bool

Whether the if exists form was present in the source.

names: ThinVec<ObjectName>

Names in source order.

behavior: Option<DropBehavior>

Optional behavior for this syntax.

meta: Meta

Source location and node identity.

Trait Implementations

impl Clone for DropStatement

fn clone(&self) -> DropStatement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DropStatement

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DropStatement

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for DropStatement

impl Hash for DropStatement

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,

impl PartialEq for DropStatement

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

Equality operator ==.

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

Inequality operator !=.

impl Render for DropStatement

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

Return the render for this value.

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.

impl Serialize for DropStatement

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Spanned for DropStatement

fn span(&self) -> Span

Return the span for this value.
