Struct jet_margin::Invocation

#[repr(transparent)]
pub struct Invocation { /* private fields */ }

Data made available to invoked programs by the margin program. Put data here if:

• adapters need a guarantee that the margin program is the actual source of the data, or
• the data is needed by functions defined in margin that are called by adapters Note: The security of the margin program cannot rely on function calls that happen within adapters, because adapters can falsify the arguments to those functions. Rather, this data should only be used to enable adapters to protect themselves, in which case it would be in their best interest to pass along the actual state from the margin account.
