Implementations

impl MongodbBuilder

pub fn connection_string(self, v: &str) -> Self

Available on crate feature services-mongodb only.

Set the connection_string of the MongoDB service.

This connection string is used to connect to the MongoDB service. It typically follows the format:

Format

Examples:

• Connecting to a local MongoDB instance: mongodb://localhost:27017
• Using authentication: mongodb://myUser:myPassword@localhost:27017/myAuthDB
• Specifying authentication mechanism: mongodb://myUser:myPassword@localhost:27017/myAuthDB?authMechanism=SCRAM-SHA-256

Options

• authMechanism: Specifies the authentication method to use. Examples include SCRAM-SHA-1, SCRAM-SHA-256, and MONGODB-AWS.
• … (any other options you wish to highlight)

For more information, please refer to MongoDB Connection String URI Format.
