Feature request: Customize pointer types #2023
Comments

Not opposed to this, seems like a reasonable thing to want. Curious about your use case, can you customize the header? Introducing an annotation for this should be straight-forward. Adding some sort of configuration seems a bit more tricky because we need a way to target fields and such which I don't think we have atm. |

I prefer not to customize the header. This is being generated from linux uapi headers. I don't need a way to target things though, I want this to apply universally. |

Ah, alright, then it should also be trivial. A patch that checks the context options here: rust-bindgen/src/codegen/mod.rs Line 3612 in c39c47c Or even here: rust-bindgen/src/codegen/mod.rs Line 351 in c39c47c Would do and should be straight-forward. |
These options allow specifying an alternate type to use where pointer types would otherwise be used. This is useful for binding to a WebAssembly guest, as well as for certain kinds of serialization and deserialization. Resolves rust-lang#2023.

I'd like to be able to customize the types of pointer types generated by bindgen. That is, the input:
would produce the output:
where
CustomPointeris an arbitrary type path specified in configuration.The idea here is the custom pointer type can be a safe transparent wrapper around an integer value, which can e.g. treat the pointer as belonging to another process and read it from there.
