Struct PoolConfig 

#[non_exhaustive]
pub struct PoolConfig {
    pub max_size: u32,
    pub min_idle: Option<u32>,
    pub max_lifetime: Option<Duration>,
    pub idle_timeout: Option<Duration>,
    pub connect_timeout: Duration,

}

Available on crate feature database and non-WebAssembly only.

Represents a pool config.

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_size: u32

The max size.

min_idle: Option<u32>

The min idle.

max_lifetime: Option<Duration>

The max lifetime.

idle_timeout: Option<Duration>

The idle timeout.

connect_timeout: Duration

The connect timeout.

max_connections: u32

The max connections.

min_connections: u32

The min connections.

acquire_timeout: Duration

The acquire timeout.

test_before_acquire: bool

The test before acquire.

Implementations

impl PoolConfig

pub fn new() -> PoolConfig

Create a new pool configuration with default values

Examples

use reinhardt_db::pool::PoolConfig;

let config = PoolConfig::new();
assert_eq!(config.max_connections, 10);

pub fn with_max_connections(self, max: u32) -> PoolConfig

Sets the max connections and returns self for chaining.

pub fn with_min_connections(self, min: u32) -> PoolConfig

Sets the min connections and returns self for chaining.

pub fn with_connection_timeout(self, timeout: Duration) -> PoolConfig

Sets the connection timeout and returns self for chaining.

pub fn with_connect_timeout(self, timeout: Duration) -> PoolConfig

Sets the connect timeout and returns self for chaining.

pub fn with_acquire_timeout(self, timeout: Duration) -> PoolConfig

Sets the acquire timeout and returns self for chaining.

pub fn with_max_lifetime(self, lifetime: Option<Duration>) -> PoolConfig

Sets the max lifetime and returns self for chaining.

pub fn with_idle_timeout(self, timeout: Option<Duration>) -> PoolConfig

Sets the idle timeout and returns self for chaining.

pub fn with_test_before_acquire(self, test: bool) -> PoolConfig

Sets the test before acquire and returns self for chaining.

pub fn validate(&self) -> Result<(), String>

Performs the validate operation.
