How to get the number of vertices contained within a Canvas?

Since a Canvas is limited to 65535 vertices, i thought there must be a way to retrieve the current amount of vertices a Canvas contains.

I'm working on a graph visualizer using Vectrosity and i will most likely surpass the 65k limitation, so i wrote a class that creates a new Canvas if the vertex limit is reached. Instead of keeping track of the vertex count, i would rather query the Canvas for the current amount of vertices...this should be possible imo...

• A Canvas does not contain a MeshFilter component, so it's not possible to retrieve the amount of vertices from the Mesh of that MeshFilter.

• The Canvas component itself doesn't provide any info on the number of vertices.

• Any ideas?
