Episode notes
ABIs and Rust
- ABIs define how systems call functions, differing per platform.
- Rust uses the C ABI for cross-compiler compatibility due to its unstable ABI.
Rust ABI Documentation
- Rust's ABI, used for function pointers in Rust-to-Rust calls, is documented.
- Guarantees for ABI compatibility are now specified for types like pointers and integers.
Type Names from References
type_name
returns a string representation of a type, useful for debugging.type_name_of_val
extends this to print type names from instances where naming a generic type is impossible.
