Variants

CreateEntity

Fields

name: String

fields: Vec<FieldSpec>

AddField

Fields

entity: String

field: FieldSpec

RemoveField

Fields

entity: String

field_name: String

AlterField

Change column shape on an existing field. Only nullable transitions today (required → optional, optional → required); type changes stay manual because they can fail on existing rows in ways the planner can’t reason about (e.g. string → int on a column with non-numeric values).

Real-world driver: pylon-cloud’s User entity made avatarColor optional after the framework’s OAuth handler started failing USER_CREATE_FAILED on a NOT NULL violation. Without AlterField the manifest change was a no-op against the live PG schema — operators had to drop NOT NULL by hand. Now the planner emits the ALTER and pylon dev auto-applies it on the next reload.

previous carries the old column shape so the SQL emitter can decide whether to emit DROP NOT NULL, SET NOT NULL, both, or neither. target is the desired final shape.

Fields

entity: String

previous: FieldSpec

target: FieldSpec

RemoveEntity

Fields

name: String

AddIndex

Fields

entity: String

name: String

fields: Vec<String>

unique: bool

RemoveIndex

Fields

entity: String

name: String

CreateSearchIndex

Materialize the FTS5 + facet-bitmap shadow tables for a searchable entity. Emitted alongside CreateEntity when the manifest declares a search: config; idempotent so repeated pushes against a live DB are safe.

Fields

entity: String

config: ManifestSearchConfig

RemoveSearchIndex

Drop an entity’s search shadow tables. Emitted when the entity is removed from the manifest or its search: block is cleared.

Fields

entity: String

Trait Implementations

impl Clone for SchemaOperation

fn clone(&self) -> SchemaOperation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SchemaOperation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SchemaOperation

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SchemaOperation

fn eq(&self, other: &SchemaOperation) -> 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 SchemaOperation

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for SchemaOperation

impl StructuralPartialEq for SchemaOperation
