Trait IntoRustTuple 

pub trait IntoRustTuple {
    type Tuple;

    // Required method
    fn into_rust_tuple(self) -> Self::Tuple;
}

Moves a canonical list into a native Rust tuple in logical source order.

Canonical lists terminate in CNil<()>. Native tuple bridges support zero through twelve fields; lists themselves have no arity limit. Nested list fields remain lists rather than being recursively converted or flattened. Conversion requires no cloning, equality, or formatting capabilities.

Examples

use cel_runtime::{IntoCStackList, IntoRustTuple};

let list = (String::from("left"), 7_u8, 2.5_f64).into_c_stack_list();
let value: (String, u8, f64) = list.into_rust_tuple();
assert_eq!(value, (String::from("left"), 7, 2.5));

Required Associated Types

type Tuple

The native tuple type with fields in logical source order.

Required Methods

fn into_rust_tuple(self) -> Self::Tuple

Moves each logical field into the corresponding native tuple field.

• Complexity: O(n) field moves for n fields, without heap allocation.

Examples

use cel_runtime::{IntoCStackList, IntoRustTuple};

let value: (String,) = (String::from("owned"),)
    .into_c_stack_list()
    .into_rust_tuple();
assert_eq!(value.0, "owned");

Dyn Compatibility

This trait is dyn compatible.

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