PreparedSegment

cel_runtime::prepared_segment

Struct PreparedSegment 

Source 
pub struct PreparedSegment<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: ValueRepr, R: ValueRepr> PreparedSegment<A, R>

Source

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

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.
