}

An input variant of the text field: its HTML type, the rules it contributes, and how it parameterises the one text control (extra attributes, adjacent adornments). The extension point a plugin builds on (a currency input, say) instead of reimplementing a field. An input parameterises the single text control; anything needing different control markup is a FieldType.

Required Methods

fn key(&self) -> &'static str

The registry key naming this input (text, email, url, currency).

Provided Methods

fn html_type(&self) -> &'static str

The HTML type attribute.

fn resolve_options( &self, _raw: &Value, _types: &FieldRegistry, ) -> Result<ResolvedOptions, OptionsError>

Types this input’s own keys from the field’s options blob (the same blob the field type reads) once at boot. Default: no options.

fn option_keys(&self) -> Vec<&'static str>

The keys this input reads from the field’s entry (min, max, step for a number). A key no part of the field reads is refused.

fn rules(&self, _opts: &ResolvedOptions) -> Vec<Rule>

Rules this input contributes (an email input adds Rule::Email).

fn attributes(&self, _opts: &ResolvedOptions) -> BTreeMap<String, String>

Extra <input> attributes (a number input’s min/max/step). Names are validated at boot and may not collide with the ones the template owns.

fn adornments(&self, _opts: &ResolvedOptions) -> Vec<Adornment>

Controls placed beside the input (a copy button, a currency symbol).

fn assets(&self, _opts: &ResolvedOptions) -> Vec<&'static str>

Asset-registry keys this input needs (a heavy widget’s script/style). The copy button needs none, since its island ships in core laterite.js.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
