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 declaration order.

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 normalize_values(&self, values: &mut HashMap<String, String>)

Rewrites submitted values into their fields’ stored spelling and leaves empty submissions empty for the presence rule to refuse.

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

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

pub fn unknown_keys(&self, values: &HashMap<String, String>) -> Vec<String>

Lists keys in values that no declared input owns, sorted, so handlers reject client-controlled writes.

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

Reports what is wrong with this declaration: a field whose lens binds no single column, and two fields sharing a name.

pub fn validate(&self, values: &HashMap<String, String>) -> FieldErrors

Validates submitted values against declared inputs, treating absent keys as empty and skipping fields in absent repeater groups and hidden variant groups.

pub async fn validate_async( &self, cx: &Cx, values: &HashMap<String, String>, ) -> FieldErrors

Validates submissions and then probes each visible choice’s option existence.

Trait Implementations

impl Default for Schema

fn default() -> Self

Returns the “default value” for a type.
