Struct libreda_db::rw_reference_access::hierarchy_reference_access::RwRefAccess

pub struct RwRefAccess<T> {
    base: Arc<RwLock<T>>,
}

Wrapper around a Netlist or Layout, etc. into a Arc<RwLock<_>> to provide save read and write access. Access is checked at runtime. If only read access is required, then it might be more efficient to use crate::reference_access.

In contrast to the API of HierarchyBase and others the object-like API avoids returning iterators but returns vectors of elements. This allows to keep the lock-time short.

Fields

base: Arc<RwLock<T>>

Implementations
