Struct ConnectorPoolOptions 

pub struct ConnectorPoolOptions { /* private fields */ }

Optional overrides for the sqlx connection pool and statement cache used by Nautilus executors.

Any field left unset preserves the backend-specific defaults used by crate::PgExecutor::new, crate::MysqlExecutor::new, or crate::SqliteExecutor::new.

Implementations

impl ConnectorPoolOptions

pub const fn new() -> Self

Create an empty set of pool overrides.

pub fn max_connections(self, max_connections: u32) -> Self

Override the maximum number of pooled connections.

pub fn min_connections(self, min_connections: u32) -> Self

Override the minimum number of pooled connections kept warm.

pub fn acquire_timeout(self, acquire_timeout: Duration) -> Self

Override the maximum time spent waiting for a pooled connection.

pub fn idle_timeout(self, idle_timeout: impl Into<Option<Duration>>) -> Self

Override the maximum idle duration for pooled connections.

Pass None to disable idle reaping entirely.

pub fn test_before_acquire(self, test_before_acquire: bool) -> Self

Override whether sqlx pings a connection before returning it from the pool.

pub fn statement_cache_capacity(self, statement_cache_capacity: usize) -> Self

Override the per-connection statement cache capacity used by sqlx.

Set this to 0 to disable statement caching entirely.

pub const fn get_max_connections(&self) -> Option<u32>

Return the configured maximum-connection override, if any.

pub const fn get_min_connections(&self) -> Option<u32>

Return the configured minimum-connection override, if any.

pub const fn get_acquire_timeout(&self) -> Option<Duration>

Return the configured acquire-timeout override, if any.

pub const fn get_idle_timeout(&self) -> Option<Option<Duration>>

Return the configured idle-timeout override, if any.

None means “use the executor default”. Some(None) means “disable idle timeout”. Some(Some(duration)) sets a custom timeout.

pub const fn get_test_before_acquire(&self) -> Option<bool>

Return the configured test_before_acquire override, if any.

pub const fn get_statement_cache_capacity(&self) -> Option<usize>

Return the configured statement-cache-capacity override, if any.

Trait Implementations

impl Clone for ConnectorPoolOptions

fn clone(&self) -> ConnectorPoolOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ConnectorPoolOptions

impl Debug for ConnectorPoolOptions

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

Formats the value using the given formatter.

impl Default for ConnectorPoolOptions

fn default() -> ConnectorPoolOptions

Returns the “default value” for a type.

impl Eq for ConnectorPoolOptions

impl PartialEq for ConnectorPoolOptions

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

Tests for self and other values to be equal, and is used by ==.

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

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