Struct PreparedSegment 

Source 
pub struct PreparedSegment<A, R>
where
    A: ValueRepr,
    R: ValueRepr,
{ /* private fields */ }
Expand description

Owns a frozen raw body with exact canonical argument/result witnesses.

Calls borrow arguments, clone only emitted reads, and return independent owners.

Implementations§

Source§

impl<A, R> PreparedSegment<A, R>
where A: ValueRepr, R: ValueRepr,

Source

pub fn call( &mut self, args: &<A as ValueRepr>::Value, ) -> Result<<R as ValueRepr>::Value, Error>

Executes without shape comparisons, checked conversions, or Any downcasts.

  • Postcondition: The input remains borrowed and every returned owner is independent.
§Errors

Propagates the original operation error and its context after frame cleanup.

  • Complexity: O(a) pointer setup for a arguments plus body/clone costs.
§Examples

See the module example.
