Module core 

Core types for rustango.

This crate is dependency-light on purpose: no async, no DB drivers, no proc-macros. Anything that needs to be referenced by both the macro output and the runtime lives here.

Structs

AdminConfig

Django ModelAdmin-shape per-model admin customization. Populated by the Model derive when the struct carries #[rustango(admin(...))].

AggregateQuery

A SELECT … GROUP BY … HAVING … query. Returned rows are untyped (HashMap<String, SqlValue>) because the projection is dynamic.

Assignment

One column = value pair in an UPDATE ... SET ... clause.

BulkInsertQuery

Compiled multi-row INSERT — one round-trip for N rows.

BulkUpdateQuery

Bulk per-row UPDATE using UPDATE t SET … FROM (VALUES …). One row in the VALUES clause per input item; the PK identifies which table row to update.

CheckConstraint

Descriptor for one table-level CHECK constraint.

CompositeFkRelation

Multi-column (“composite”) foreign key relation, declared at the model level rather than the field level — single-column FKs stay in FieldSchema::relation, composite FKs live here so each participating column keeps its plain Rust type.

CountQuery

Compiled SELECT COUNT(*) — same shape as a DeleteQuery (model + where clause); the writer emits COUNT(*) projection and no LIMIT/OFFSET.

DeleteQuery

Compiled DELETE.

FieldSchema

Static description of a single column on a model.

Fieldset

One group of fields on a create/edit form (slice 10.5).

Filter

One predicate in a WHERE clause: column <op> value. Always the leaf of a WhereExpr tree.

GenericRelation

Generic (“any model”) foreign key declared at the model level — pairs a content_type_id column with an object_pk column whose values together identify a row in any registered model. The pointed-at model varies per row.

IndexSchema

Descriptor for one CREATE INDEX emitted by the migration writer.

InsertQuery

returning names columns the writer should append after RETURNING — used for Auto<T> PKs, where the row is inserted with the column omitted so Postgres’ sequence DEFAULT fires, and the assigned value is then read back into the model.

Join

A LEFT JOIN against a target model.

M2MRelation

Descriptor for one many-to-many relation declared via #[rustango(m2m(name = "tags", to = "app_tags", through = "post_tags", src = "post_id", dst = "tag_id"))].

ModelSchema

Static description of a model.

OrderClause

Single column in an ORDER BY clause. Slice 9.0b.

SearchClause

(col1 ILIKE %q% OR col2 ILIKE %q% …) — single-parameter case-insensitive substring match across multiple columns. Used by the admin’s ?q=… box.

SelectQuery

Compiled SELECT over a single model with an optional WHERE clause expressed as a WhereExpr tree.

TypedAssignment

An Assignment tagged with the model it applies to.

TypedExpr

Typed boolean expression — a TypedFilter tree composed with .and() / .or(). Constructed implicitly from any TypedFilter via Into, so callers usually never name this type:

TypedFilter

A Filter tagged with the model it applies to.

UpdateQuery

Compiled UPDATE.

Enums

AggregateExpr

One aggregate expression in an AggregateQuery.

ConflictClause

Compiled INSERT of a single row.

FieldType

Kind of value stored in a column.

ModelScope

Where a model’s table lives in a tenancy deployment. Mirrors crate::migrate::MigrationScope but on the model side, so the migration generator can route changes to the right scoped file without touching the runtime schema-discovery path.

Op

Comparison operator on a single column.

QueryError

Error raised while building or compiling a QuerySet.

Relation

Static description of a relation to another model.

SqlValue

A typed value that can be bound to a query parameter.

WhereExpr

Boolean expression in a WHERE clause — leaf Filters composed with AND / OR to arbitrary depth.

Traits

Column

A typed reference to a single scalar column on Self::Model.

Model

Trait every #[derive(Model)] struct implements.

Functions

infer_app_label_from_module_path

Parse the Rust module path produced by module_path!() and return the first segment after the crate root, or None when the model lives at the project root. Public so callers (admin, makemigrations CLI, the diagnostic manage list-apps verb) can apply the same inference rules to module-path strings they already have.

validate_value

Validate a single bound value against its field’s declared bounds.

version

Returns the crate version. Used by the workspace smoke test.
