Attribute Macro structible 

#[structible]

Transforms a struct into a map-backed type with generated accessors.

Example

use structible::structible;

#[structible(HashMap)]
pub struct Person {
    pub name: String,
    pub age: u32,
    pub email: Option<String>,
}

This generates:

• A field enum for map keys (one variant per field)
• A value enum for map values (wrapping each field type)
• A PersonFields struct for ownership extraction
• The Person struct backed by HashMap
• Getters, setters, and removers for each field

Optional Fields

Fields typed as Option<T> are stored without the Option wrapper. Presence in the map represents Some, absence represents None:

• email() returns Option<&String>
• set_email(v) inserts the value
• remove_email() removes and returns the value if present

Required Fields

Non-optional fields are guaranteed present after construction:

• name() returns &String (not Option)
• set_name(v) replaces the value
• Use into_fields() then take_name() to extract owned value
