Functions ¶
func NumberGenContractId ¶
func NumberGenContractId() string
NumberGenContractId returns the capability contract id for this interface
func NumberGenHandler ¶
NumberGenHandler is called by an actor during `main` to generate a dispatch handler The output of this call should be passed into `actor.RegisterHandlers`
Types ¶
type NumberGen ¶
type NumberGen interface {
//
// GenerateGuid - return a 128-bit guid in the form 123e4567-e89b-12d3-a456-426655440000
// These guids are known as "version 4", meaning all bits are random or pseudo-random.
//
GenerateGuid(ctx *actor.Context) (string, error)
// Request a random integer within a range
// The result will will be in the range [min,max), i.e., >= min and < max.
RandomInRange(ctx *actor.Context, arg RangeLimit) (uint32, error)
// Request a 32-bit random number
Random32(ctx *actor.Context) (uint32, error)
}
type NumberGenReceiver ¶
type NumberGenReceiver struct{}
NumberGenReceiver receives messages defined in the NumberGen service interface
type NumberGenSender ¶
type NumberGenSender struct {
// contains filtered or unexported fields
}
NumberGenSender sends messages to a NumberGen service
func NewProviderNumberGen ¶
func NewProviderNumberGen() *NumberGenSender
NewProvider constructs a client for sending to a NumberGen provider implementing the 'wasmcloud:builtin:numbergen' capability contract, with the "default" link
func NewProviderNumberGenLink ¶
func NewProviderNumberGenLink(linkName string) *NumberGenSender
NewProviderNumberGenLink constructs a client for sending to a NumberGen provider implementing the 'wasmcloud:builtin:numbergen' capability contract, with the specified link name
func (*NumberGenSender) GenerateGuid ¶
func (s *NumberGenSender) GenerateGuid(ctx *actor.Context) (string, error)
GenerateGuid - return a 128-bit guid in the form 123e4567-e89b-12d3-a456-426655440000 These guids are known as "version 4", meaning all bits are random or pseudo-random.
func (*NumberGenSender) Random32 ¶
func (s *NumberGenSender) Random32(ctx *actor.Context) (uint32, error)
Request a 32-bit random number
func (*NumberGenSender) RandomInRange ¶
func (s *NumberGenSender) RandomInRange(ctx *actor.Context, arg RangeLimit) (uint32, error)
Request a random integer within a range The result will will be in the range [min,max), i.e., >= min and < max.
type RangeLimit ¶
Input range for RandomInRange, inclusive. Result will be >= min and <= max Example: random_in_range(RangeLimit{0,4}) returns one the values, 0, 1, 2, 3, or 4.
func CDecodeRangeLimit ¶
func CDecodeRangeLimit(d *cbor.Decoder) (RangeLimit, error)
CDecodeRangeLimit deserializes a RangeLimit using cbor
func MDecodeRangeLimit ¶
func MDecodeRangeLimit(d *msgpack.Decoder) (RangeLimit, error)
MDecodeRangeLimit deserializes a RangeLimit using msgpack
