Rust makes heavy use of FFI to call out to C, and C doesn't use segmented stacks, so Rust assumes they need 2MiB of stack space.
If we get rid of everything in the standard library calling out to C, it might just mean a reasonable 10-30% performance hit but I don't see that happening soon. _______________________________________________ Rust-dev mailing list [email protected] https://mail.mozilla.org/listinfo/rust-dev
