type Request 

type Request struct {
	ID   string `json:"@id,omitempty"`
	Type string `json:"@type,omitempty"`
	// Comment is an optional field that provides human readable information about this Credential Offer,
	// so the offer can be evaluated by human judgment.
	// TODO: Should follow DIDComm conventions for l10n. [Issue #1300]
	Comment string `json:"comment,omitempty"`
	// RequestsAttach is a slice of attachments defining the requested formats for the credential
	RequestsAttach []decorator.Attachment `json:"requests~attach,omitempty"`

	Thread *decorator.Thread `json:"~thread,omitempty"`
}

Request is a message sent by the potential Holder to the Issuer, to request the issuance of a credential. Where circumstances do not require a preceding Offer Credential message (e.g., there is no cost to issuance that the Issuer needs to explain in advance, and there is no need for cryptographic negotiation), this message initiates the protocol.
