Release Notes

mmastrac/rust-ctor (ctor)

v0.12.0

Added

• Support for #[ctor] on impl items. To be valid, the fn must have no
  self parameter and must not access any generic parameters from the outer
  item.
• Added life before main documentation to all crates.
• early and late priority values are now supported on all platforms.

Removed

• deprecated dtor feature and crate dependency from ctor crate (use the dtor crate directly).

Fixed

• AIX uses "standard" priority values from 0 to 999, early and late (mapped to
  8000000 to 8000099).

Changed

• If the priority feature is enabled, ctor priority sorting is now stable
  and consistent across platforms: early/0/unspecified, then 1 <= N < 1000, then late.
• If a link_section or export_name_prefix is specified, a priority value
  must not be specified (now a compiler error).
• Migrated to using the linktime-proc-macro crate for proc-macro support.
