type ReadParams

type ReadParams struct {
	Handle StreamHandle `json:"handle"`           // Handle of the stream to read.
	Offset int64        `json:"offset,omitempty"` // Seek to the specified offset before reading (if not specificed, proceed with offset following the last read). Some types of streams may only support sequential reads.
	Size   int64        `json:"size,omitempty"`   // Maximum number of bytes to read (left upon the agent discretion if not specified).
}

ReadParams read a chunk of the stream.
