Crate siderite_orm 

siderite-orm: backend-neutral ORM core.

• Model / ModelMeta: models and their static metadata, generated by #[derive(Model)].
• QuerySet: lazy, immutable queries compiled into a QueryPlan.
• Expr / Field: the typed expression DSL (Django Q, F, lookups).
• WritePlan: INSERT / UPDATE / DELETE.
• Db: the handle application code uses (pool or transaction).
• Executor / Backend / Transaction: implemented by adapters in siderite-backends; plans are checked against BackendCapabilities before any I/O.

This crate has no HTTP dependencies; the HTTP layer converts OrmError into API errors.

Modules

backend

Executor, backend and transaction traits implemented by database adapters.

capabilities

Backend capability model.

db

Db: the database handle application code passes around.

decode

Typed decoding of dynamic result rows: FromValues for values_list, Row::get_as and QueryResult::decode for raw SQL.

error

ORM error hierarchy. HTTP mapping lives in siderite-core.

expr

Typed expression AST (Django Q / F / lookup equivalents).

model

The Model trait and its static ModelMeta.

ops

Instance operations: ModelOps gives every Model save, delete and refresh (Django Model.save() / delete() / refresh_from_db()).

plan

QueryPlan: the backend-neutral intermediate representation.

queryset

QuerySet: a lazy, immutable query over one model.

relations

Relation field types.

router

Database routing: pick the database alias for reads and writes (Django DATABASE_ROUTERS).

signals

Model lifecycle signals: pre_save, post_save, pre_delete, post_delete and m2m_changed (Django django.db.models.signals).

types

Mapping between Rust field types, SQL column types and Value.

value

Backend-neutral scalar values used for bind parameters and decoded rows.

write

WritePlan: backend-neutral INSERT / UPDATE / DELETE.

Macros

params

Build a Vec<Value> of bind parameters: params![id, "name"].
