[][src]Struct mysql_async::PoolConstraints

pub struct PoolConstraints { /* fields omitted */ }

Connection pool constraints.

This type stores min and max constraints for Pool and ensures that min <= max.


impl PoolConstraints[src]

pub fn new(min: usize, max: usize) -> Option<PoolConstraints>[src]

Creates new PoolConstraints if constraints are valid (min <= max).

pub fn min(&self) -> usize[src]

Lower bound of this pool constraints.

pub fn max(&self) -> usize[src]

Upper bound of this pool constraints.
