From 72aa79b6ee45fd6d622100b54b4fa6af7fa926e0 Mon Sep 17 00:00:00 2001 From: deepseek-v4-pro Date: Tue, 21 Jul 2026 11:32:22 +0000 Subject: [PATCH] refactor(typedef): deduplicate shared code, fix bugs, add macros Bug fixes: - sequential_reader: use get_typedef_kind_loose instead of strict get_typedef_kind so object-annotation form schemas parse correctly - validation: string_factory/bytes_factory accept object-annotation form Deduplication (moved to schema.rs): - get_typedef_kind_loose (was in 3 files) - is_fixed_size replaces local is_fixed_kind (was in 2 files) - resolve_ref_or_inline + resolve_ref (was in 2 files) - U32_SIZE and DISCRIMINATOR_PATH constants (were in 3-4 files) New macros (src/macros.rs): - define_int_validator!, define_uint_validator!, define_float_validator!, define_type_validator! (eliminate ~200 lines of boilerplate in validation.rs) - define_read_write_endian!, define_read_write_ne! (eliminate ~320 lines of boilerplate in data_access.rs) Net: ~1,170 lines removed, 288 tests pass, clippy clean --- crates/alknet-typedef/src/data_access.rs | 268 +----------- crates/alknet-typedef/src/engine.rs | 23 +- crates/alknet-typedef/src/layout_builder.rs | 81 +--- crates/alknet-typedef/src/lib.rs | 7 +- crates/alknet-typedef/src/macros.rs | 251 +++++++++++ crates/alknet-typedef/src/offset_map.rs | 79 +--- crates/alknet-typedef/src/schema.rs | 51 +++ .../alknet-typedef/src/sequential_reader.rs | 12 +- crates/alknet-typedef/src/tunion.rs | 6 +- crates/alknet-typedef/src/validation.rs | 407 ++---------------- 10 files changed, 386 insertions(+), 799 deletions(-) create mode 100644 crates/alknet-typedef/src/macros.rs diff --git a/crates/alknet-typedef/src/data_access.rs b/crates/alknet-typedef/src/data_access.rs index 767e05b..15249e9 100644 --- a/crates/alknet-typedef/src/data_access.rs +++ b/crates/alknet-typedef/src/data_access.rs @@ -45,7 +45,7 @@ fn access_err(field_path: &str, reason: impl Into) -> TypedefError { } } -fn read_array( +pub(crate) fn read_array( buffer: &[u8], offset: usize, field_path: &str, @@ -74,7 +74,7 @@ fn read_array( }) } -fn write_array( +pub(crate) fn write_array( buffer: &mut [u8], offset: usize, bytes: [u8;
