gdb doesn't have a way to know when an object hasn't yet been
initialized, and in this case, if a pretty-printer returns an absurd
number of children, this can result in apparent hangs in some modes.
This came up specifically with DAP, see this bug report:
https://sourceware.org/bugzilla/show_bug.cgi?id=33594
This patch (mostly) addresses this potential issue in the Rust
pretty-printers, by adding 'num_children' methods. In particular a
method like this is added when the number of children is variable and
also relatively easy to compute. (I.e., I didn't attempt the btree
printers.)
Supplying num_children is good for DAP regardless of the
initialization problem, because DAP requires a count of child objects
and this is more efficient than enumerating the children, which is
gdb's fallback approach.

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
