Key:

  • Exactly the same features in both the driver and the ArangoDB version.
  • + Features included in the driver may be not present in the ArangoDB API. Calls to ArangoDB may result in unexpected responses (404).
  • - The ArangoDB version has features that are not supported by the driver.

Overview

Package driver implements a Go driver for the ArangoDB database.

To get started, create a connection to the database and wrap a client around it.

// Create an HTTP connection to the database
conn, err := http.NewConnection(http.ConnectionConfig{
	Endpoints: []string{"http://localhost:8529"},
})
if err != nil {
	// Handle error
}
// Create a client
c, err := driver.NewClient(driver.ClientConfig{
	Connection: conn,
})
if err != nil {
	// Handle error
}

User provides access to a single user of a single server / cluster of servers.

type UserOptions

type UserOptions struct {
	// The user password as a string. If not specified, it will default to an empty string.
	Password string `json:"passwd,omitempty"`
	// A flag indicating whether the user account should be activated or not. The default value is true. If set to false, the user won't be able to log into the database.
	Active *bool `json:"active,omitempty"`
	// A JSON object with extra user information. The data contained in extra will be stored for the user but not be interpreted further by ArangoDB.
	Extra interface{} `json:"extra,omitempty"`
}

UserOptions contains options for creating a new user, updating or replacing a user.

type V8ContextStats

type V8ContextStats struct {
	Available int64         `json:"available"`
	Busy      int64         `json:"busy"`
	Dirty     int64         `json:"dirty"`

	Max       int64         `json:"max"`
	Memory    []MemoryStats `json:"memory"`
}

V8ContextStats contains statistics about V8 contexts.

type Version

type Version string

Version holds a server version string. The string has the format "major.minor.sub". Major and minor will be numeric, and sub may contain a number or a textual version.

func (Version) CompareTo

func (v Version) CompareTo(other Version) int

CompareTo returns an integer comparing two version. The result will be 0 if v==other, -1 if v < other, and +1 if v > other. If major & minor parts are equal and sub part is not a number, the sub part will be compared using lexicographical string comparison.

func (Version) Major

func (v Version) Major() int

Major returns the major part of the version E.g. "3.1.7" -> 3

func (Version) Minor

func (v Version) Minor() int

Minor returns the minor part of the version. E.g. "3.1.7" -> 1

func (Version) Sub

func (v Version) Sub() string

Sub returns the sub part of the version. E.g. "3.1.7" -> "7"

func (Version) SubInt

func (v Version) SubInt() (int, bool)

SubInt returns the sub part of the version as integer. The bool return value indicates if the sub part is indeed a number. E.g. "3.1.7" -> 7, true E.g. "3.1.foo" -> 0, false

type VersionInfo

type VersionInfo struct {
	// This will always contain "arango"
	Server string `json:"server,omitempty"`
	//  The server version string. The string has the format "major.minor.sub".
	// Major and minor will be numeric, and sub may contain a number or a textual version.
	Version Version `json:"version,omitempty"`
	// Type of license of the server
	License string `json:"license,omitempty"`
	// Optional additional details. This is returned only if the context is configured using WithDetails.
	Details map[string]interface{} `json:"details,omitempty"`
}

VersionInfo describes the version of a database server.

func (*VersionInfo) IsEnterprise

func (v *VersionInfo) IsEnterprise() bool

func (VersionInfo) String

func (v VersionInfo) String() string

String creates a string representation of the given VersionInfo.

type VertexConstraints

type VertexConstraints struct {
	// From contains names of vertex collection that are allowed to be used in the From part of an edge.
	From []string
	// To contains names of vertex collection that are allowed to be used in the To part of an edge.
	To []string
}

VertexConstraints limit the vertex collection you can use in an edge.

type View

type View interface {
	// Name returns the name of the view.
	Name() string

	// Type returns the type of this view.
	Type() ViewType

	// ArangoSearchView returns this view as an ArangoSearch view.
	// When the type of the view is not ArangoSearch, an error is returned.
	ArangoSearchView() (ArangoSearchView, error)

	// ArangoSearchViewAlias returns this view as an ArangoSearch view alias.
	// When the type of the view is not ArangoSearch alias, an error is returned.
	ArangoSearchViewAlias() (ArangoSearchViewAlias, error)

	// Database returns the database containing the view.
	Database() Database

	// Rename renames the view (SINGLE server only).
	Rename(ctx context.Context, newName string) error

	// Remove removes the entire view.
	// If the view does not exist, a NotFoundError is returned.
	Remove(ctx context.Context) error
}

View provides access to the information of a view. Views are only available in ArangoDB 3.4 and higher.

type ViewType

type ViewType string

ViewType is the type of view.
