rust api: recursivly print tree via Debug trait if alternate flag is set

[lolbinarycat]

Problem

the Debug trait only shows the root node of a tree, which is frequently unhelpful.

Expected behavior

when printing Tree or Node with {:#?}, the implementation of Debug would recurse into child nodes and print the full AST. this would allow easier debugging.

[ObserverOfTime]

Debug printing a node does recursively print the S-exp.

[lolbinarycat]

do you mean printing with Display? i didn't check that, but it seems unintuitive that using Debug would give less info than Display.

[ObserverOfTime]

Oh yeah, it's Display.

What would recursively printing a node in the Debug format look like?

tree-sitter/lib/binding_rust/lib.rs

Lines 1484 to 1487 in 6368017

	"{{Node {} {} - {}}}",
	self.kind(),
	self.start_position(),
	self.end_position()

hmm.. i feel like i would want to use newlines and indentation to align things honestly... also it should print field names ideally.

[ObserverOfTime]

Well, you can submit a PR if you want. Maybe make it tree-like.

[lolbinarycat]

what about also making the alternate form of Display print in an indented way?

[ObserverOfTime]

Already done.
