Types

type Code 

type Code int

Code is the error code. 

const (
	// 0 ~ 99 general error
	Ok             Code = 0
	Internal       Code = 1
	NotAuthorized  Code = 2
	Invalid        Code = 3
	NotFound       Code = 4
	Conflict       Code = 5
	NotImplemented Code = 6

	// 101 ~ 199 db error
	DbConnectionFailure    Code = 101
	DbStatementSyntaxError Code = 102
	DbExecutionError       Code = 103

	// 201 db migration error
	// Db migration is a core feature, so we separate it from the db error
	MigrationSchemaMissing   Code = 201
	MigrationAlreadyApplied  Code = 202
	MigrationOutOfOrder      Code = 203
	MigrationBaselineMissing Code = 204
	MigrationPending         Code = 205
	MigrationFailed          Code = 206

	// 301 task error
	TaskTimingNotAllowed Code = 301

	// 10001 advisor error code
	CompatibilityDropDatabase  Code = 10001
	CompatibilityRenameTable   Code = 10002
	CompatibilityDropTable     Code = 10003
	CompatibilityRenameColumn  Code = 10004
	CompatibilityDropColumn    Code = 10005
	CompatibilityAddPrimaryKey Code = 10006
	CompatibilityAddUniqueKey  Code = 10007
	CompatibilityAddForeignKey Code = 10008
	CompatibilityAddCheck      Code = 10009
	CompatibilityAlterCheck    Code = 10010
	CompatibilityAlterColumn   Code = 10011
)

type Error 

type Error struct {
	// Machine-readable error code.

}

Error represents an application-specific error. Application errors can be unwrapped by the caller to extract out the code & message.

Any non-application error (such as a disk error) should be reported as an Internal error and the human user should only see "Internal error" as the message. These low-level internal error details should only be logged and reported to the operator of the application (not the end user).
