Struct FnOf 

pub struct FnOf<A, R>(/* private fields */);

Names a callable with a complete canonical parameter and result signature.

The shared carrier always clones, regardless of argument/result capabilities. Equality and default construction are not implied.

Examples

use cel_runtime::{FnOf, Nil, Leaf, ValueRepr, Callable, CNil};
let _: <FnOf<Nil, Leaf<i32>> as ValueRepr>::Value =
    Callable::from_fn(|_: &CNil<()>| Ok(7));

Non-list arguments cannot authorize a callable representation:

use cel_runtime::{FnOf, Leaf, ValueRepr};
let _ = FnOf::<Leaf<()>, Leaf<i32>>::value_type();

Trait Implementations

impl<A, R> ValueRepr for FnOf<A, R>

where A: ArgumentList, R: ValueRepr,

fn value_type() -> ValueType

Describes every parameter and result node with canonical carrier ownership.

• Complexity: O(n) time and storage for n signature nodes.

type Value = Callable<<A as ValueRepr>::Value, <R as ValueRepr>::Value>

The concrete, owned Rust representation.
