General instructions

• If this PR adds or updates a recipe, use "Add" or "Update" appropriately as the first word in its title.
• New recipes not directly relevant to the biological sciences need to be submitted to the conda-forge channel instead of Bioconda.
• PRs require reviews prior to being merged. Once your PR is passing tests and ready to be merged, please issue the @BiocondaBot please add label command.
• Please post questions on Gitter or ping @bioconda/core in a comment.

Instructions for avoiding API, ABI, and CLI breakage issues

Conda is able to record and lock (a.k.a. pin) dependency versions used at build time of other recipes.
This way, one can avoid that expectations of a downstream recipe with regards to API, ABI, or CLI are violated by later changes in the recipe.
If not already present in the meta.yaml, make sure to specify run_exports (see here for the rationale and comprehensive explanation).
Add a run_exports section like this:

build:
  run_exports:
    - ...

with ... being one of:

Case	run_exports statement
semantic versioning	{{ pin_subpackage("myrecipe", max_pin="x") }}
semantic versioning (0.x.x)	{{ pin_subpackage("myrecipe", max_pin="x.x") }}
known breakage in minor versions	{{ pin_subpackage("myrecipe", max_pin="x.x") }} (in such a case, please add a note that shortly mentions your evidence for that)
known breakage in patch versions	{{ pin_subpackage("myrecipe", max_pin="x.x.x") }} (in such a case, please add a note that shortly mentions your evidence for that)
calendar versioning	{{ pin_subpackage("myrecipe", max_pin=None) }}

while replacing "myrecipe" with either name if a name|lower variable is defined in your recipe or with the lowercase name of the package in quotes.

I would also suggest following the conda-forge documentation for bundling licenses from dependencies. https://conda-forge.org/docs/maintainer/adding_pkgs/#rust. re: #50800

[mbhall88]

as you have a build.sh, adding this script: directive will make the build not use that script I believe. Move the cargo-bundle-licenses --format yaml --output THIRDPARTY.yml into the build.sh. Take a look at https://github.com/conda-forge/ssubmit-feedstock/tree/main/recipe for an example

And while I'm being annoying, I might also recommend adding --no-track to the install command conda-forge/conda-forge.github.io#2191
