Modules

ExecutionCidState
InterpreterOutcome
Describes a result returned at the end of the interpreter execution_step.
LastError
This struct is intended to track the last arisen error. LastError is essentially a scalar value with support of lambda expressions. The only differences from a scalar are
ResolvedTriplet
ResolvedTriplet represents peer network location with all variables, literals and etc resolved into final string. This structure contains a subset of values that SecurityTetraplet consists of.
RunParameters
Parameters that a host side should pass to an interpreter and that necessary for execution.
SecurityTetraplet
Describes an origin that set corresponding value.

CatchableError
Catchable errors arisen during AIR script execution. Catchable here means that these errors could be handled by a xor instruction and their error_code could be used in a match instruction.
ExecutionError
Errors arisen while executing AIR script. This enum is pub since it’s used in tests.
FarewellError
Errors happened during the interpreter farewell step.
LambdaError
Describes errors related to applying lambdas to values.
LastErrorObjectError
Describes errors related to converting a scalar into error object.
PreparationError
Errors happened during the interpreter preparation step.
UncatchableError
Uncatchable errors arisen during AIR script execution. Uncatchable here means that these errors couldn’t be handled by a xor instruction and their error_code couldn’t be used in a match instruction. They are similar to JVM runtime errors and some of them could be caught only while execution of AIR script, others (FoldStateNotFound and MultipleVariablesFound) are checked additionally on the validation step, and presence here for convenience.
