Struct mongodb::options::ListCollectionsOptions

#[non_exhaustive]
pub struct ListCollectionsOptions {
    pub batch_size: Option<u32>,
    pub comment: Option<Bson>,
}

Specifies the options to a Database::list_collections operation.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

batch_size: Option<u32>

The number of documents the server should return per cursor batch.

Note that this does not have any affect on the documents that are returned by a cursor, only the number of documents kept in memory at a given time (and by extension, the number of round trips needed to return the entire set of documents returned by the query).

comment: Option<Bson>

Tags the query with an arbitrary Bson value to help trace the operation through the database profiler, currentOp and logs.

This option is only available on server versions 4.4+.

Implementations

impl ListCollectionsOptions

pub fn builder() -> ListCollectionsOptionsBuilder<((), ())>
