type AutoEncryptionOptions added in v1.2.0 

type AutoEncryptionOptions struct {
	KeyVaultClientOptions *ClientOptions
	KeyVaultNamespace     string
	KmsProviders          map[string]map[string]interface{}
	SchemaMap             map[string]interface{}
	BypassAutoEncryption  *bool
	ExtraOptions          map[string]interface{}
}

AutoEncryptionOptions represents options used to configure auto encryption/decryption behavior for a mongo.Client instance.

Automatic encryption is an enterprise only feature that only applies to operations on a collection. Automatic encryption is not supported for operations on a database or view, and operations that are not bypassed will result in error. Too bypass automatic encryption for all operations, set BypassAutoEncryption=true.

Auto encryption requires the authenticated user to have the listCollections privilege action.

If automatic encryption fails on an operation, use a MongoClient configured with bypassAutoEncryption=true and use ClientEncryption.encrypt() to manually encrypt values.

Enabling Client Side Encryption reduces the maximum document and message size (using a maxBsonObjectSize of 2MiB and maxMessageSizeBytes of 6MB) and may have a negative performance impact.

func (*ClientOptions) ApplyURI added in v1.0.0 

func (c *ClientOptions) ApplyURI(uri string) *ClientOptions

ApplyURI parses the given URI and sets options accordingly. The URI can contain host names, IPv4/IPv6 literals, or an SRV record that will be resolved when the Client is created. When using an SRV record, TLS support is implictly enabled. Specify the "tls=false" URI option to override this.

If the connection string contains any options that have previously been set, it will overwrite them. Options that correspond to multiple URI parameters, such as WriteConcern, will be completely overwritten if any of the query parameters are specified. If an option is set on ClientOptions after this method is called, that option will override any option applied via the connection string.

If the URI format is incorrect or there are conflicing options specified in the URI an error will be recorded and can be retrieved by calling Validate.

For more information about the URI format, see https://docs.mongodb.com/manual/reference/connection-string/. See mongo.Connect documentation for examples of using URIs for different Client configurations.

2. "zlib" - requires server version >= 3.6

3. "zstd" - requires driver version >= 1.2.0, server version >= 4.2, and cgo support to be enabled.

To use compression, it must be enabled on the server as well. If this option is specified, the driver will perform a negotiation with the server to determine a common list of of compressors and will use the first one in that list when performing operations. See https://docs.mongodb.com/manual/reference/program/mongod/#cmdoption-mongod-networkmessagecompressors for more information about how to enable this feature on the server.

func (c *ClientOptions) SetTLSConfig(cfg *tls.Config) *ClientOptions

SetTLSConfig specifies a tls.Config instance to use use to configure TLS on all connections created to the cluster. This can also be set through the following URI options:

1. "tls" (or "ssl"): Specify if TLS should be used (e.g. "tls=true").

2. "tlsCertificateKeyFile" (or "sslClientCertificateKeyFile"): Specify the path to the client certificate key file or the client private key file. If they are both needed, the files should be concatentated into one file. For example, "tlsCertificateKeyFile=/path/to/ca.pem".

3. "tlsCertificateKeyFilePassword" (or "sslClientCertificateKeyPassword"): Specify the password to decrypt the client private key file (e.g. "tlsCertificateKeyFilePassword=password").

4. "tlsCaFile" (or "sslCertificateAuthorityFile"): Specify the path to a single or bundle of certificate authorities to be considered trusted when making a TLS connection (e.g. "tlsCaFile=/path/to/caFile").

5. "tlsInsecure" (or "sslInsecure"): Specifies whether or not certificates and hostnames received from the server should be validated. If true (e.g. "tlsInsecure=true"), the TLS library will accept any certificate presented by the server and any host name in that certificate. Note that setting this to true makes TLS susceptible to man-in-the-middle attacks and should only be done for testing.

The default is nil, meaning no TLS will be enabled.

func (*ClientOptions) SetWriteConcern added in v0.1.0 

func (c *ClientOptions) SetWriteConcern(wc *writeconcern.WriteConcern) *ClientOptions

2. "wTimeoutMS": Specify how long write operations should wait for the correct number of nodes to acknowledge the operation (e.g. "wTimeoutMS=1000").

3. "journal": Specifies whether or not write operations should be written to an on-disk journal on the server before returning (e.g. "journal=true").

The default is nil, meaning the server will use its configured default.

}

Credential can be used to provide authentication options when configuring a Client.

AuthMechanism: the mechanism to use for authentication. Supported values include "SCRAM-SHA-256", "SCRAM-SHA-1", "MONGODB-CR", "PLAIN", "GSSAPI", and "MONGODB-X509". This can also be set through the "authMechanism" URI option. (e.g. "authMechanism=PLAIN"). For more information, see https://docs.mongodb.com/manual/core/authentication-mechanisms/.

3. SERVICE_REALM: The service realm for GSSAPI authentication.

4. SERVICE_HOST: The host name to use for GSSAPI authentication. This should be specified if the host name to use for authentication is different than the one given for Client construction.

The SERVICE_HOST and CANONICALIZE_HOST_NAME properties must not be used at the same time on Linux and Darwin systems.

Username: the username for authentication. This can also be set through the URI as a username:password pair before the first @ character. For example, a URI for user "user", password "pwd", and host "localhost:27017" would be "mongodb://user:pwd@localhost:27017". This is optional for X509 authentication and will be extracted from the client certificate if not specified.

Password: the password for authentication. This must not be specified for X509 and is optional for GSSAPI authentication.

PasswordSet specifies if the password is actually set, since an empty password is a valid password.
