Struct ConnectionLimits 

Source 
pub struct ConnectionLimits { /* private fields */ }
Expand description

Resolved connection-permit policy for disposable database leases.

The budget models downstream application connections. Each live database lease reserves Self::connections_per_database permits, so the effective lease limit is floor division and any remainder stays unused. Harness-owned owner, template-coordination, and lifecycle-administration sessions are separate from this application budget.

Implementations§

Source§

impl ConnectionLimits

Source

pub const fn connection_budget(&self) -> usize

Returns the total number of downstream-connection permits.

Source

pub const fn connections_per_database(&self) -> u32

Returns the permits reserved by every live database lease.

This value should cover the sum of the maximum sizes of every application pool or standalone connection that one test can open.

Source

pub const fn max_simultaneous_leases(&self) -> usize

Returns the effective maximum number of simultaneous database leases.

This is connection_budget / connections_per_database, rounded down.
