Struct mongodb::event::cmap::ConnectionPoolOptions

#[non_exhaustive]
pub struct ConnectionPoolOptions {
    pub max_idle_time: Option<Duration>,
    pub max_pool_size: Option<u32>,
    pub min_pool_size: Option<u32>,
}

Contains the options for creating a connection pool. While these options are specified at the client-level, ConnectionPoolOptions is exposed for the purpose of CMAP event handling.

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.

max_idle_time: Option<Duration>

Connections that have been ready for usage in the pool for longer than max_idle_time will not be used.

The default is that connections will not be closed due to being idle.

max_pool_size: Option<u32>

The maximum number of connections that the pool can have at a given time. This includes connections which are currently checked out of the pool.

The default is 100.

min_pool_size: Option<u32>

The minimum number of connections that the pool can have at a given time. This includes connections which are currently checked out of the pool. If fewer than min_pool_size connections are in the pool, connections will be added to the pool in the background.

The default is that no minimum is enforced

Trait Implementations

impl Clone for ConnectionPoolOptions

fn clone(&self) -> ConnectionPoolOptions

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConnectionPoolOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ConnectionPoolOptions

fn default() -> ConnectionPoolOptions

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ConnectionPoolOptions

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<ConnectionPoolOptions> for ConnectionPoolOptions

fn eq(&self, other: &ConnectionPoolOptions) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ConnectionPoolOptions

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.
