Struct Schema 

pub struct Schema { /* private fields */ }

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

Implementations

impl Schema

pub fn is_empty(&self) -> bool

Reports whether this schema declares nothing to render.

pub fn new(children: impl IntoSchema) -> Self

Builds a Schema from any IntoSchema and reports duplicate field names as declaration errors.

pub fn empty() -> Self

pub fn fields(&self) -> impl Iterator<Item = &Field>

Every field, in the order it joins the schema: a layout’s fields as it composes, in declaration order, and an embedded value’s fields when it binds.

pub fn bind(self, db: &Db) -> Self

Binds the schema’s embedded values and embedded paths to db’s app schema.

A panel binds the schemas it mounts; bind one a custom page renders before rendering it. A schema with no embedded value or path is bound from the start.

pub async fn render<'a>( &self, cx: &'a Cx, source: Source<'_>, ) -> Result<BoxView<'a>>

Renders the schema from source and fails with declaration errors instead of rendering.

Errors

A misdeclared schema fails with its errors rather than render.

pub fn extend(self, other: Schema) -> Schema

Appends another schema’s nodes after this one’s.

pub fn declaration_errors(&self) -> Vec<DeclarationErrorKind>

Reports what is wrong with this declaration: an embedded value or path never bound, a field whose lens binds no single column, and two fields sharing a name.

impl Default for Schema

fn default() -> Self

Returns the “default value” for a type.
