Struct MaxConnections 

pub struct MaxConnections(/* private fields */);

Maximum number of database connections in the pool.

MaxConnections represents the connection pool size limit. It must be at least 1, enforced by using NonZeroU32 as the underlying type.

Examples

use eventcore_postgres::MaxConnections;
use std::num::NonZeroU32;

let small_pool = MaxConnections::new(NonZeroU32::new(5).expect("5 is non-zero"));
let standard = MaxConnections::new(NonZeroU32::new(10).expect("10 is non-zero"));
let large_pool = MaxConnections::new(NonZeroU32::new(50).expect("50 is non-zero"));

// Zero connections not allowed by type system
// let zero = NonZeroU32::new(0); // Returns None

Implementations

impl MaxConnections

pub fn new(raw_value: NonZeroU32) -> Self

impl MaxConnections

pub fn into_inner(self) -> NonZeroU32

Trait Implementations

impl AsRef<NonZero<u32>> for MaxConnections

fn as_ref(&self) -> &NonZeroU32

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for MaxConnections

fn clone(&self) -> MaxConnections

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MaxConnections

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

Formats the value using the given formatter.

impl Display for MaxConnections

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

Formats the value using the given formatter.

impl From<MaxConnections> for NonZeroU32

fn from(value: MaxConnections) -> Self

Converts to this type from the input type.

impl PartialEq for MaxConnections

fn eq(&self, other: &MaxConnections) -> 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.
