Struct SelectOption 

pub struct SelectOption<T = Value>
where
    T: Serialize + DeserializeOwned + JsonSchema,
{
    pub value: T,
    pub label: String,
    pub description: Option<String>,
}

An option in a StandardRequest::Select request.

Each option has:

• value: Machine-readable identifier returned in the response (generic over T)
• label: Human-readable text displayed to the user
• description: Optional additional context about the option

The type parameter T defaults to serde_json::Value for backwards compatibility.

Wire Format

{
  "value": "prod",
  "label": "Production",
  "description": "Live environment - requires approval"
}

Example

use plexus_core::plexus::bidirectional::SelectOption;

let options = vec![
    SelectOption::new("minimal", "Minimal Starter")
        .with_description("Basic project structure"),
    SelectOption::new("full", "Full Featured")
        .with_description("All features included"),
    SelectOption::new("api", "API Only"),  // No description
];

Fields

value: T

Machine-readable value returned when this option is selected.

This is what appears in StandardResponse::Selected. Should be a stable identifier (e.g., “dev”, “prod”, “option_1”).

label: String

Human-readable label displayed to the user.

Should be concise but descriptive (e.g., “Development”, “Production”).

description: Option<String>

Optional description providing additional context.

Use for longer explanations that don’t fit in the label. Clients may display this as a tooltip or secondary text.

Implementations

impl SelectOption

pub fn new(value: impl Into<Value>, label: impl Into<String>) -> SelectOption

Create a new select option with value and label.

This constructor is for the default T = serde_json::Value type. The value parameter is converted to serde_json::Value via .into().

Arguments

• value - Machine-readable identifier (returned in response), convertible to serde_json::Value
• label - Human-readable display text

Example

use plexus_core::plexus::bidirectional::SelectOption;

let opt = SelectOption::new("dev", "Development Environment");
assert_eq!(opt.label, "Development Environment");

pub fn with_description(self, desc: impl Into<String>) -> SelectOption

Add a description to this option.

Example

use plexus_core::plexus::bidirectional::SelectOption;

let opt = SelectOption::new("prod", "Production")
    .with_description("Live environment - changes affect real users");

assert_eq!(opt.description, Some("Live environment - changes affect real users".into()));

impl<T> SelectOption<T>

where T: Serialize + DeserializeOwned + JsonSchema,

pub fn new_typed(value: T, label: impl Into<String>) -> SelectOption<T>

Create a new select option with a typed value and label.

Use this constructor when working with a custom type T.

Arguments

• value - The typed value for this option
• label - Human-readable display text

pub fn with_description_typed(self, desc: impl Into<String>) -> SelectOption<T>

Add a description to this option.

Trait Implementations

impl<T> Clone for SelectOption<T>

where T: Clone + Serialize + DeserializeOwned + JsonSchema,

fn clone(&self) -> SelectOption<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for SelectOption<T>

where T: Debug + Serialize + DeserializeOwned + JsonSchema,

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for SelectOption<T>

where T: Serialize + DeserializeOwned + JsonSchema,

fn deserialize<__D>( __deserializer: __D, ) -> Result<SelectOption<T>, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> JsonSchema for SelectOption<T>

where T: Serialize + DeserializeOwned + JsonSchema,

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl<T> PartialEq for SelectOption<T>

where T: PartialEq + Serialize + DeserializeOwned + JsonSchema,

fn eq(&self, other: &SelectOption<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> Serialize for SelectOption<T>

where T: Serialize + DeserializeOwned + JsonSchema,

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<T> StructuralPartialEq for SelectOption<T>

where T: Serialize + DeserializeOwned + JsonSchema,
