seg := capnp.NewBuffer(nil) structType, _ := capnp.NewStruct(seg, capnp.StructSize(8, 4)) newStruct, _ := capnp.NewStruct(seg, structType.StructSize())
seg := capnp.NewBuffer(nil) structType, _ := capnp.NewStruct(seg, capnp.StructSize(8, 4)) newStruct, _ := capnp.NewStruct(seg, structType.StructSize()) // set values on the struct newStruct.SetUint8Field(0, 1) newStruct.SetUint32Field(1, 2)In this example, a new Cap'n Proto buffer is created with a nil slice. A new struct type is then created with a size of 8 bytes for the first field and 4 bytes for the second field. A new struct is created on the segment with the newly created struct type. The two fields of the struct are then set to 1 (Uint8) and 2 (Uint32). Overall, the go-capnproto package provides tools for working with Cap'n Proto data serialization format in Go.
