Detailed Description

Member Typedef Documentation

Default

using RPCArg::Default = UniValue

Default constant value.

Definition at line 202 of file util.h.

DefaultHint

using RPCArg::DefaultHint = std::string

Hint for default value.

Definition at line 200 of file util.h.

Fallback

using RPCArg::Fallback = std::variant<Optional, DefaultHint, Default>

Definition at line 203 of file util.h.

Member Enumeration Documentation

Optional

enum RPCArg::Optional

strong

Enumerator
NO	Required arg.
OMITTED	Optional argument for which the default value is omitted from help text for one of two reasons: It's a named argument and has a default value of null. Its default value is implicitly clear. That is, elements in an array may not exist by default. When possible, the default value should be specified.

Definition at line 186 of file util.h.

Type

enum RPCArg::Type

strong

Enumerator
OBJ
ARR
STR
NUM
BOOL
OBJ_NAMED_PARAMS	Special type that behaves almost exactly like OBJ, defining an options object with a list of pre-defined keys. The only difference between OBJ and OBJ_NAMED_PARAMS is that OBJ_NAMED_PARMS also allows the keys to be passed as top-level named parameters, as a more convenient way to pass options to the RPC method without nesting them.
OBJ_USER_KEYS	Special type where the user must set the keys e.g. to define multiple addresses; as opposed to e.g. an options object where the keys are predefined.
AMOUNT	Special type representing a floating point amount (can be either NUM or STR)
STR_HEX	Special type that is a STR with only hex chars.
RANGE	Special type that is a NUM or [NUM,NUM].
