Types

type CallOptions 

type CallOptions struct {
	GetDocument       []gax.CallOption
	ListDocuments     []gax.CallOption
	CreateDocument    []gax.CallOption
	UpdateDocument    []gax.CallOption
	DeleteDocument    []gax.CallOption
	BatchGetDocuments []gax.CallOption
	BeginTransaction  []gax.CallOption
	Commit            []gax.CallOption
	Rollback          []gax.CallOption
	RunQuery          []gax.CallOption
	Write             []gax.CallOption
	Listen            []gax.CallOption
	ListCollectionIds []gax.CallOption
}

CallOptions contains the retry settings for each method of Client.

type Client 

type Client struct {

	// The call options for this service.
	CallOptions *CallOptions
	// contains filtered or unexported fields
}

Client is a client for interacting with Google Cloud Firestore API.

Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

func NewClient 

func NewClient(ctx context.Context, opts ...option.ClientOption) (*Client, error)

NewClient creates a new firestore client.

The Cloud Firestore service.

This service exposes several types of comparable timestamps: 

create_time - The time at which a document was created. Changes only
when a document is deleted, then re-created. Increases in a strict
monotonic fashion.

update_time - The time at which a document was last updated. Changes
every time a document is modified. Does not change when a write results
in no modifications. Increases in a strict monotonic fashion.

read_time - The time at which a particular state was observed. Used
to denote a consistent snapshot of the database or the time at which a
Document was observed to not exist.

commit_time - The time at which the writes in a transaction were
committed. Any read with an equal or greater read_time is guaranteed
to see the effects of the transaction.
Example 
ctx := context.Background()
c, err := firestore.NewClient(ctx)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use client.
_ = c

Output:

func (*Client) BatchGetDocuments 

func (c *Client) BatchGetDocuments(ctx context.Context, req *firestorepb.BatchGetDocumentsRequest, opts ...gax.CallOption) (firestorepb.Firestore_BatchGetDocumentsClient, error)

BatchGetDocuments gets multiple documents.

Documents returned by this method are not guaranteed to be returned in the same order that they were requested.

Example 
ctx := context.Background()
c, err := firestore.NewClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &firestorepb.BatchGetDocumentsRequest{
	// TODO: Fill request struct fields.
}
stream, err := c.BatchGetDocuments(ctx, req)
if err != nil {
	// TODO: Handle error.
}
for {
	resp, err := stream.Recv()
	if err == io.EOF {
		break
	}
	if err != nil {
		// TODO: handle error.
	}
	// TODO: Use resp.
	_ = resp
}

Output:

func (*Client) BeginTransaction 

func (c *Client) BeginTransaction(ctx context.Context, req *firestorepb.BeginTransactionRequest, opts ...gax.CallOption) (*firestorepb.BeginTransactionResponse, error)

BeginTransaction starts a new transaction.

Example 
ctx := context.Background()
c, err := firestore.NewClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &firestorepb.BeginTransactionRequest{
	// TODO: Fill request struct fields.
}
resp, err := c.BeginTransaction(ctx, req)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Output:

func (*Client) Close 

func (c *Client) Close() error

Close closes the connection to the API service. The user should invoke this when the client is no longer required.

func (*Client) Commit 

func (c *Client) Commit(ctx context.Context, req *firestorepb.CommitRequest, opts ...gax.CallOption) (*firestorepb.CommitResponse, error)

Commit commits a transaction, while optionally updating documents.
