Struct CoercedSchema 

pub struct CoercedSchema<T: FromStr> { /* private fields */ }

Parses strings into T: FromStr — the duality citizen with Input = String, Output = T (SC-8), mirroring HTML form input.

Implementations

impl<T: FromStr> CoercedSchema<T>

pub fn label(self, label: &'static str) -> Self

Sets the UI label metadata slot.

pub fn description(self, description: &'static str) -> Self

Sets the UI description metadata slot.

pub fn placeholder(self, placeholder: &'static str) -> Self

Sets the UI placeholder metadata slot.

Trait Implementations

impl<T: FromStr> Clone for CoercedSchema<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: FromStr> Debug for CoercedSchema<T>

Type-erased debug output.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: FromStr> Default for CoercedSchema<T>

Creates an empty schema via coerced().

fn default() -> Self

Returns the “default value” for a type.

impl<T: FromStr + 'static> DynSchema for CoercedSchema<T>

fn validate_value(&self, v: &Value) -> Vec<FormaIssue>

Validates an erased value; issues mirror what the typed parse would report.

fn shape(&self) -> &ShapeNode

Introspection node describing this schema’s kind and constraints, memoized in a per-instance cache on first call.

fn metadata(&self) -> &FieldMeta

UI-facing metadata slots attached to this schema.

impl<T: FromStr + ToValue + 'static> ObjectChild for CoercedSchema<T>

fn validate_at( &self, v: &Value, path: &FieldPath, _fail_fast: bool, ) -> Result<Value, Vec<FormaIssue>>

Validates v addressed at path (already joined by the caller); on full success returns the validated output converted to Value.

fn shape_node(&self) -> ShapeNode

Introspection projection (delegates to the child’s own shape()).

fn meta(&self) -> &FieldMeta

UI-facing metadata slots of the child (serves ObjectSchema::field_meta).

fn clone_boxed(&self) -> Box<dyn ObjectChild>

Crate-internal deep-clone seam powering ObjectSchema: Clone (Field.child is Box<dyn ObjectChild>, which cannot be duplicated without dispatch). Sealed: exactly six impls, all below.

impl<T: FromStr> Schema for CoercedSchema<T>

type Input = String

What the schema consumes.

type Output = T

What the schema produces on success.

fn parse(&self, input: &Self::Input) -> Result<Self::Output, FormaError>

Validates and parses input; all violated constraints accumulate into one error.
