Shared types

Objects shared between services. Provides common serialization <-> deserialization. Particularly useful when passing objects via RMQ.

QuoteRequest

type QuoteRequest struct {
	Stock      string
	UserID     string
	AllowCache bool
	ID         uint64
}

qr := QuoteRequest{ "AAPL", "jappleseed", true, 1}

qr.ToCSV() // "AAPL,jappleseed,true,1"

qr2, err := ParseQuoteRequest("AAPL,jappleseed,true,1")

Quote

• Price is serialized as a float
• Timestamp is serialized as milliseconds from the epoch

type Quote struct {
	Price     currency.Currency
	Stock     string
	UserID    string
	Timestamp time.Time
	Cryptokey string
}

tenDollars, _ := currency.NewFromFloat(10.0)
q := Quote{tenDollars, "AAPL", "jappleseed", time.Now(), "abc123="}

q.ToCSV() // "10.00,AAPL,jappleseed,123456789,abc123="

q2, err := ParseQuote("10.00,AAPL,jappleseed,123456789,abc123=")

AuditEvent

• Format for passing items through the audit_event RMQ channel
• Should map to the columns in the Logs table
• EventType should be an enum with entries
  • command: User commands. One per transaction!
  • account_action: Changes to a user's account state.
  • quote: Shouldn't have to be used since quotes aren't logged using the audit_event RMQ channel
• Content can be the formatted xml for commands or quotes, or semi-structured text for account actions

type AuditEvent struct {
	UserID    string
	ID        uint64
	EventType string
	Content   string
}

ae := AuditEvent{"jappleseed", uint64(1), "command", "DO THIS NOW"}

ae.ToCSV() // "jappleseed,1,command,DO THIS NOW"

ae2, err := ParseAuditEvent("jappleseed,1,command,DO THIS NOW")

DumplogRequest

• Filename specifies the name for the create file on the audit log server

type DumplogRequest struct {
	UserID   string
	Filename string
}

dr := DumplogRequest{"jappleseed", "ja-dumplog"}

dr.ToCSV() // "jappleseed,ja-dumplog"

dr2, err := ParseDumplogRequest("jappleseed,ja-dumplog")
