# Build configuration for keydr.
#
# HISTORY: this file once contained aggressive workarounds (LTO disabled,
# opt-level dropped to 1) because release builds consumed 5+ GB and never
# finished on a 4-core / 7.6 GB VM. That was NOT a hardware limitation —
# it was a codegen bug in rust-i18n v3, fixed by upgrading to v4.
#
# With rust-i18n v4 the same machine does a full opt-level=3 + thin-LTO
# release build with a 2.08 GB peak in 3m25s. See docs/BUILDING.md.
#
# What remains here is ordinary small-machine hygiene, not a handicap:
# nothing below reduces the optimisation level of shipped code.

[build]
# Cap parallelism at 3 of 4 cores. This is about keeping the machine
# interactive (SSH stays responsive during a build), not about memory.
# Remove it if you don't care about using the box while it compiles.

    # Use the lld that ships with the Rust toolchain. GNU ld is
    # single-threaded and holds the whole link graph in memory; lld is
    # faster and leaner. The -B flag is the stable-Rust way to select it
    # (`-Clink-self-contained=+linker` requires nightly).
    #
    # If you move this repo to another machine, update this path or
    # install system lld and use plain `-fuse-ld=lld`.

# NOTE: [profile.release] is deliberately absent — cargo's defaults
# (opt-level = 3, codegen-units = 16, no LTO) are correct for this project
# now. Add `lto = "thin"` if you want it; measured at 2.08 GB peak / 3m25s
# on this box, which is comfortable.
