Module Tezos_raw_protocol_012_Psithaca.Ticket_scanner
Source
This module provides an API for extracting tickets of arbitrary types from an OCaml values, given a type-witness.
type ex_ticket =
| Ex_ticket : 'a Script_typed_ir.comparable_ty * 'a Script_typed_ir.ticket -> ex_ticket
A type for representing existentially quantified tickets (tickets with different types of payloads). An ex_ticket
value consists of:
- A type-witness representing the type of the content of the ticket.
- A ticket value of the particular content type.
val tickets_of_value :
Alpha_context.context ->
include_lazy:bool ->
'a Script_typed_ir.ty ->
'a ->
(ex_ticket list * Alpha_context.context)

tickets_of_value ctxt ~include_lazy ty value
extracts all tickets from the given shape ty
and value value
. The include_lazy
flag determines whether or not to traverse lazy structures (values from the context). In case the include_lazy
flag is true
, any big-map contained in the value must have an empty overlay or else an error of type Unsupported_non_empty_overlay
is returned. The reason for this restriction is that we assume that all lazy big-map diffs should be applied before calling this function. Dealing with non-empty overlays would be possible in theory, but practically difficult. The challenge is to distinguish between overlapping keys between the context and the overlay.
