# M7 Handoff 02 (RFC-027): the v1.2-vs-v2 benchmark comparison. Pinned exactly
# (not "1.2") so a fresh resolve can't silently pick up a later 1.2.x with
# different behaviour than what was measured. Renamed so both major versions
# coexist in one bench binary.
#
# This does NOT introduce a second calamine. v1.2.0's manifest pins
# `calamine = "0"` with no minor constraint, and a dependency's own committed
# lockfile does not constrain a consuming workspace, so Cargo unifies v1.2 and
# v2 onto the single `calamine 0.36.1` already here -- confirmed with
# `cargo tree -i calamine`. Both sides of the comparison therefore run on the
# literal same parser, which removes the largest confound the benchmark would
# otherwise have had. Do not pin calamine down for this dependency: doing so
# would manufacture exactly that confound.
#
# `cargo deny` consequently reports nothing about calamine because there is
# nothing to report -- not because `multiple-versions-include-dev` defaults to
# false. That default is real and is what covers the pre-existing zip 7.2/8.6
# dev-only split (see deny.toml's comment); it is unrelated to this.
sheets-diff-v1_2 = { package = "sheets-diff", version = "=1.2.0" }
# Test-only: patches a generated xlsx's internal XML (e.g. workbookPr
# date1904, a raw t="d" cell) to reach calamine code paths rust_xlsxwriter's
# public API cannot produce (RFC-035 Handoff 05, D-01/D-02 reachability).
# Version and feature set matched exactly to calamine's own `zip` dependency
# (version = "8.6", features = ["deflate"], default-features = false) so
# this reuses the already-resolved 8.6.0 with no new transitive deps —
# `zip`'s default features pull in ppmd/lzma/bzip2/aes codecs this crate
# does not use and one of which (ppmd-rust) fails the license allowlist.
