Would like to add parsing of newick format just to print the newick in the first place. Newick is described here:https://en.wikipedia.org/wiki/Newick_format. It is possible to get multiple newick trees inside a single file, they each finish with a semicolon. Some trees can have many nodes, the structure is a graph-type with nodes, edges and leaves. There is an XML format that some python programs parse newick into, phyloXML
Describe the solution you'd like
Looking to start a module phylo.rs with a parse of newick into some type of good struct or hashmap in the first place, with just ability to print it out.
Describe alternatives you've considered
There are some newick tree parsers in crates.io but they all seem to be a few years old, for example newick_0.11.0
Additional context
Various types of newick tree to parse: The one below marked as "popular" is the one I've seen much the most often, so we could concentrate on that structure and allow the others if possible. There are multiple nodes.
(,,(,)); no nodes are named
(A,B,(C,D)); leaf nodes are named
(A,B,(C,D)E)F; all nodes are named
(:0.1,:0.2,(:0.3,:0.4):0.5); all but root node have a distance to parent
(:0.1,:0.2,(:0.3,:0.4):0.5):0.0; all have a distance to parent
(A:0.1,B:0.2,(C:0.3,D:0.4):0.5); distances and leaf names (popular)
(A:0.1,B:0.2,(C:0.3,D:0.4)E:0.5)F; distances and all names
((B:0.2,(C:0.3,D:0.4)E:0.5)F:0.1)A; a tree rooted on a leaf node (rare)
