Trait HierarchyView

pub trait HierarchyView<'a>: RootTagged + Sized {
    // Required method
    fn try_new(hugr: &'a impl HugrView, root: Node) -> Result<Self, HugrError>;
}

A common trait for views of a HUGR hierarchical subgraph.

Required Methods

fn try_new(hugr: &'a impl HugrView, root: Node) -> Result<Self, HugrError>

Create a hierarchical view of a HUGR given a root node.

Errors

Returns HugrError::InvalidTag if the root isn’t a node of the required OpTag

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
