Module odata 

OData integration for SeaORM with security-scoped pagination.

This module provides SeaORM-specific adapters for OData queries:

• OData filter compilation to SeaORM conditions (legacy FieldMap and new FilterNode)
• Cursor-based pagination with OData ordering
• Security-scoped pagination via OPager builder

Filter DSL

The core filter types (FilterField, FilterNode, FilterOp, FieldKind) are defined in modkit-odata as part of the OData protocol contract. Import them from:

use modkit_odata::filter::{FilterField, FilterNode, FilterOp, FieldKind};

Modules

• core: Core OData to SeaORM translation (filters, cursors, ordering) - legacy FieldMap based
• sea_orm_filter: Type-safe mapping from FilterNode<F> to SeaORM conditions
• pager: Fluent builder for secure + OData pagination

Traits

CursorApplyExt

Extension trait for applying cursor-based pagination

ODataExt

Apply an optional OData filter (via wrapper) to a plain SeaORM Select.

ODataOrderExt

Extension trait for applying ordering (legacy version with ODataBuildError)

ODataOrderPageExt

Extension trait for applying ordering with centralized error handling

ODataQueryExt

Extension trait for applying full OData query (filter + cursor + order)

Functions

build_cursor_for_model

Build a cursor from a model using the effective order and field map extractors.

build_cursor_predicate

Build a cursor predicate for pagination. This builds the lexicographic OR-chain condition for cursor-based pagination.

ensure_tiebreaker

Ensure a tiebreaker field is present in the order

expr_to_condition

Convert an OData filter expression AST to a SeaORM Condition.

paginate_with_odata

One-shot pagination combiner that handles filter → cursor predicate → order → overfetch/trim → build cursors.
