Types

type BotCommand

type BotCommand struct {
	Help  helpCommand   `json:"-"`
	Quote quoteCommand  `json:"quote,omitempty"`
	Track trackCommand  `json:"track,omitempty"`
	Alert usecase.Alert `json:"alert,omitempty"`
}

The commands are parsed from UserCommand into BotCommand. quoteCommand and trackCommand are almost identical in their usecases, so they share quoteCommand, which has []usecase.Security. On the other hand, alertCommand is imported directly as usecase.Alert, which also has usecase.Security (not slice).

type ParseError

type ParseError int

const (
	// These errors are non-zero
	NoErr ParseError = iota
	ErrParseInt
	ErrParseFloat
	ErrInvalidSign
	ErrInvalidBidAskSwitch
	ErrInvalidQuoteTypeBid
	ErrInvalidQuoteTypeAsk
	ErrInvalidQuoteTypeLast
)

type UserCommand

type UserCommand struct {
	Text      string        `json:"chat,omitempty"`
	TargetBot enums.BotType `json:"command,omitempty"`
}

The commands are parsed from UserCommand into BotCommand. quoteCommand and trackCommand are almost identical in their usecases, so they share quoteCommand, which has []usecase.Security. On the other hand, alertCommand is imported directly as usecase.Alert, which also has usecase.Security (not slice).

func (UserCommand) Parse

func (c UserCommand) Parse() (cmd BotCommand, e ParseError)

Parse parses UserCommand to BotCommand
