Enum SetScope 

pub enum SetScope {
    Session,
    Local,
    Global,
}

The scope qualifier on a SET/RESET: SESSION (the default), LOCAL, or GLOBAL.

SESSION/LOCAL are the PostgreSQL SET scopes; GLOBAL is a DuckDB RESET scope (RESET GLOBAL x), reached only through SessionStatement::Reset under UtilitySyntax::reset_scope — the PostgreSQL SET grammar never yields it.

Variants

Session

SET SESSION — apply for the whole session.

Local

SET LOCAL — apply only until the current transaction ends.

Global

SET GLOBAL — apply server-wide (MySQL).

Trait Implementations

impl Clone for SetScope

fn clone(&self) -> SetScope

Returns a duplicate of the value.

Performs copy-assignment from source.

impl Copy for SetScope

impl Debug for SetScope

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

impl<'de> Deserialize<'de> for SetScope

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

impl Eq for SetScope

impl Hash for SetScope

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 SetScope

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

Equality operator ==.

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

Inequality operator !=.

impl Render for SetScope

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 SetScope

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
