[−][src]Struct mysql_async::PoolConstraints
Connection pool constraints.
This type stores min
and max
constraints for Pool
and ensures that min <= max
.
Methods
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.
