Module schema 

Unified Schema primitive — fields and layout blocks that compose via view!.

Schema holds layout blocks, embedded values, and Field slots and resolves every field once into one list for rendering and validation.

Re-exports

pub use lenses::FieldResolver;

Structs

ChoiceField

A choice field: Field::choice.

ControlInput

What a Control renders for one form: the field’s key, its current value, and its validation state.

CustomField

A field an app’s Control renders: Field::custom and Field::toggle.

Field

One form field binding a lens to the control editing it, offering only that control’s modifiers so a modifier on the wrong control does not compile.

FieldResolver

The app schema embedded paths resolve through: the compiled schema of the app’s Db.

FileField

A file field: Field::file.

Grid

Holds a column container with cols clamped to 1..12.

Group

Holds an unlabelled container for grouping fields.

Schema

Composes fields and layout blocks and resolves every field once into one list.

Section

Holds a titled container with an optional child Schema.

Source

Holds where a schema render reads field values and errors from for a form or a read-only view.

TextField

A text field: Field::text.

Toggle

Renders a bool field as a checkbox preceded by a hidden false, displaying as "Yes"/"No".

Constants

MAX_RELATIONSHIP_OPTIONS

Caps the options a relationship choice field loads instead of scanning a large table per select.

Traits

Control

Renders a field’s input from a ControlInput and its stored value for display, using a hidden field for a state that submits nothing.

EmbeddedForm

Reads an embedded value from and writes it to the flat form map; derive it to generate the value’s schema.

IntoOptions

A choice’s static options as (value, label) pairs, in display order.

IntoSchema

Converts a field, a layout block, a tuple of either, or a schema into a Schema.

OptionSource

Describes the source a relationship option loader reads.

Options

A closed set of stored values, each with its label.

TypedValue

Parses a typed column’s text submission and names the type in the error it produces.
