Reads For Messages

Message interface

MsgReadsForRequest RequestReadsFor

type RequestReadsFor :=
  mkRequestReadsFor@{
    externalIdentityA : ExternalIdentity;
    externalIdentityB : ExternalIdentity;
  };

A request to query whether externalIdentityA can read data encrypted to externalIdentityB.

Arguments
externalIdentityA:
The identity doing the reading.
externalIdentityB:
The identity being read for.

MsgReadsForResponse ResponseReadsFor

type ResponseReadsFor :=
  mkResponseReadsFor@{
    readsFor : Bool;
    err : Option String;
  };

Response indicating whether the reads_for relationship exists.

Arguments
readsFor:
True if externalIdentityA can read for externalIdentityB, False otherwise.
err:
An error message if the query failed.

MsgSubmitReadsForEvidenceRequest RequestSubmitReadsForEvidence

type RequestSubmitReadsForEvidence :=
  mkRequestSubmitReadsForEvidence@{
    evidence : ReadsForEvidence;
  };

Request to submit evidence of a reads_for relationship.

Arguments
evidence:
The evidence supporting the reads_for relationship.

MsgSubmitReadsForEvidenceResponse ResponseSubmitReadsForEvidence

type ResponseSubmitReadsForEvidence :=
  mkResponseSubmitReadsForEvidence@{
    err : Option String;
  };

Response acknowledging the submission of evidence.

Arguments
err:
An error message if the submission failed.

MsgQueryReadsForEvidenceRequest RequestQueryReadsForEvidence

type RequestQueryReadsForEvidence :=
  mkRequestQueryReadsForEvidence@{
    externalIdentity : ExternalIdentity;
  };

Request to query all reads_for evidence related to an identity.

Arguments
externalIdentity:
The identity for which to retrieve evidence.

MsgQueryReadsForEvidenceResponse ResponseQueryReadsForEvidence

type ResponseQueryReadsForEvidence :=
  mkResponseQueryReadsForEvidence@{
    externalIdentity : ExternalIdentity;
    evidence : Set ReadsForEvidence;
    err : Option String;
  };

Response providing the requested evidence.

Arguments
externalIdentity:
The identity for which evidence was requested.
evidence:
A set of ReadsForEvidence related to the identity.
err:
An error message if the query failed.
