Enum mongodb::options::CursorType
source · [−]#[non_exhaustive]
pub enum CursorType {
NonTailable,
Tailable,
TailableAwait,
}
Expand description
Specifies the type of cursor to return from a find operation.
Variants (Non-exhaustive)
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
NonTailable
Default; close the cursor after the last document is received from the server.
Tailable
Do not close the cursor after the last document is received from the server. If more results become available later, the cursor will return them.
TailableAwait
Similar to Tailable
, except that the cursor should block on receiving more results if
none are available.
