tlopex opened a new pull request, #682:
URL: https://github.com/apache/tvm-ffi/pull/682
This PR adds Rust `match_any!`, using source-ordered conditional dispatch.
Each typed pattern is tried in declaration order, a false guard continues to
the next arm, and a final fallback arm is required. It also supports borrowed
values and dynamic object hierarchy matching while strengthening the related
Object, Tensor, allocator, and FFI safety boundaries.
```rust
match_any! {
expr {
TypedExpr::<TensorType>(tensor)
if tensor.shape.length() == 2 => {
lower_tensor(tensor, func_context)
},
TypedExpr::<ShapedType>(shaped) => {
lower_shaped(shaped, func_context)
},
_ => {
report_unsupported(func_context)
},
}
}
```
