Enum StorageKind 

pub enum StorageKind {
    Plain,
    External,
    Extended,
    Main,
}

Per-column TOAST storage strategy.

Mirrors Postgres pg_attribute.attstorage (p|e|x|m). The semantic effective value depends on the column’s data type; see crate::ir::canon::filter_pg_defaults for how an explicit Some(default) is stripped to None so source and catalog round-trip equally.

Variants

Plain

PLAIN — inline only, never TOASTed or compressed.

External

EXTERNAL — out-of-line allowed, compression forbidden.

Extended

EXTENDED — out-of-line and compression allowed (default for most variable-width types).

Main

MAIN — compression allowed inline, out-of-line only as a last resort.

Trait Implementations

impl Clone for StorageKind

fn clone(&self) -> StorageKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StorageKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StorageKind

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for StorageKind

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 PartialEq for StorageKind

fn eq(&self, other: &StorageKind) -> 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 Serialize for StorageKind

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for StorageKind
