}

An extension trait for HugrView which provides methods that delegate to HugrView and then return the result in FatNode form. See for example FatExt::fat_io.

TODO: Add the remaining HugrView equivalents that make sense.

Provided Methods

fn try_fat<OT>( &self, node: Self::Node, ) -> Option<FatNode<'_, OT, Self, Self::Node>>

where for<'a> &'a OpType: TryInto<&'a OT>,

Try to create a specific FatNode for a given Node.

fn fat_optype(&self, node: Self::Node) -> FatNode<'_, OpType, Self, Self::Node>

Create a general FatNode for a given Node.

fn fat_io( &self, node: Self::Node, ) -> Option<(FatNode<'_, Input, Self, Self::Node>, FatNode<'_, Output, Self, Self::Node>)>

Try to create Input and Output FatNodes for a given Node. This will succeed only for DataFlow Parent Nodes.

fn fat_children( &self, node: Self::Node, ) -> impl Iterator<Item = FatNode<'_, OpType, Self, Self::Node>>

Create general FatNodes for each of a Node’s children.

fn fat_root<OT>(&self) -> Option<FatNode<'_, OT, Self, Self::Node>>

where for<'a> &'a OpType: TryInto<&'a OT>,

Try to create a specific FatNode for the root of a HugrView.

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.
