Attribute Macro derive_type_get 

#[derive_type_get]

Derive get methods for types that retrieve interned types.

Note: It is suggested to use the pliron_type macro instead of using this macro directly. The documention here is useful though, because pliron_type’s generate_get field expands to this macro.

This macro generates appropriate get methods based on the struct’s fields:

• For unit structs: generates a singleton get(ctx: &Context) method
• For structs with fields (named or tuple): generates a get(ctx: &mut Context, ...) method

Examples

Named fields struct:

use pliron::derive::{def_type, derive_type_get, format_type, verify_succ};
use pliron::context::Context;

#[verify_succ]
#[def_type("my_dialect.vector_type")]
#[format_type]
#[derive_type_get]  // Auto-generates get method
#[derive(Debug, Clone, PartialEq, Eq, Hash)]
pub struct VectorType {
    elem_ty: u32,
    num_elems: u32,
}

// Usage of the auto-generated get method:
let vector_type = VectorType::get(ctx, 42, 8); // get(ctx, elem_ty, num_elems)

Tuple struct:

use pliron::derive::{def_type, derive_type_get, format_type, verify_succ};
use pliron::context::Context;

#[verify_succ]
#[def_type("my_dialect.tuple_type")]
#[format_type]
#[derive_type_get]  // Auto-generates get method
#[derive(Debug, Clone, PartialEq, Eq, Hash)]
pub struct TupleType(u32, String, bool);

// Usage of the auto-generated get method:
let tuple_type = TupleType::get(ctx, 42, "hello".to_string(), true); // get(ctx, field_0, field_1, field_2)

Unit struct:

use pliron::derive::{def_type, derive_type_get, format_type, verify_succ};
use pliron::context::Context;

#[verify_succ]
#[def_type("my_dialect.unit_type")]
#[format_type]
#[derive_type_get]  // Auto-generates singleton get method
#[derive(Debug, Clone, PartialEq, Eq, Hash)]
pub struct UnitType;

// Usage of the auto-generated singleton get method:
let unit_type = UnitType::get(ctx); // get(ctx) - no additional parameters
