API review and stability documentation for v1.0.0 #54

Copilot · 2025-12-14T06:56:27Z

Comprehensive API review confirming readiness for v1.0.0 stable release. All 42 public macros, 34 functions, and 7 feature flags reviewed. No breaking changes required.

Documents Added

API_REVIEW_V1.0.0.md (13K) - Technical analysis of entire API surface, compatibility assessment, security review. Recommendation: Approved with high confidence.
STABILITY_POLICY.md (9.5K) - Semantic versioning guarantees, MSRV policy (1.77.0, updates allowed in minor versions only), deprecation process (3 minor version warning period).
CHANGELOG.md (5.6K) - Release history following Keep a Changelog format. Documents v1.0.0 as stability commitment with zero breaking changes from v0.7.1.
RELEASE_CHECKLIST_V1.0.0.md (4.9K) - Step-by-step publishing guide including critical ordering requirement (proc-macro before main crate).
REVIEW_SUMMARY.md (4.8K) + V1_0_0_REVIEW_README.md (6.5K) - Executive summaries and navigation guide.

Key Findings

API Surface Validated:

42 public macros stable (concat, split, parse, format, etc.)
34 const functions across 7 modules
6 stable + 1 experimental feature flags
__ctfe and __proc modules properly hidden (not part of stability contract)

Quality Confirmed:

158 tests passing (100% pass rate)
Zero security vulnerabilities
All linting/formatting passes
Excellent documentation coverage

Migration Path:

# v0.7.1 → v1.0.0: No code changes required
const-str = "1.0"  # Just update version

V1_0_0_REVIEW_README.md

+- 13 Core string operations
+- 9 Comparison & search operations
+- 8 Conversion & encoding operations
+- 4 Format & case operations


The count "4 Format & case operations" is incorrect. Based on the actual macros (format!, convert_case!, convert_ascii_case!, cstr!, raw_cstr!), there are 5 macros in this category. Update to 5.

Suggested change

- 4 Format & case operations

- 5 Format & case operations

The heading states "7 Feature Flags" but the description below lists 8 feature flags: default, std, proc, regex, http, case, all (7 stable) plus unstable (1 experimental) equals 8 total. The count should be updated to "8 Feature Flags" to be accurate.

REVIEW_SUMMARY.md

+- **42 public macros** organized by category
+- **34 public functions** across 7 modules
+- **43 internal types** (properly hidden)
+- **7 feature flags** with stability assessment


The document states "7 feature flags" but there are actually 8 feature flags in total (default, std, proc, regex, http, case, all, unstable). The count should be updated to 8.

Suggested change

- **7 feature flags** with stability assessment

- **8 feature flags** with stability assessment

Copilot · 2025-12-14T07:36:51Z

STABILITY_POLICY.md

+- `std` - Standard library support
+- `proc` - Procedural macro support
+- `regex` - Regex validation
+- `http` - HTTP header validation
+- `case` - Case conversion
+- `all` - Enable all features


The feature flags list is incomplete. It lists 6 features (std, proc, regex, http, case, all) but misses the 'default' feature flag which is also stable. For completeness, 'default' should be included in this list, bringing the total to 7 stable features. The 'unstable' feature is correctly omitted here as it's addressed separately in the "What is NOT Stable" section.

API_REVIEW_V1.0.0.md

+#### Format & Case (4 macros)
+- `format!` - Format string with interpolation (requires `proc` feature)
+- `convert_ascii_case!` - Convert ASCII case
+- `convert_case!` - Convert to various cases (requires `case` feature)
+- `cstr!` - Create C string literal
+
+#### Advanced Features (8 macros)
+- `raw_cstr!` - Create raw C string


The categorization is inconsistent. "Format & Case (4 macros)" lists only 4 items but should include 5 macros: format!, convert_ascii_case!, convert_case!, cstr!, and raw_cstr!. Currently raw_cstr! is incorrectly placed in the "Advanced Features" section (line 76). The correct categorization should be Format & Case: 5 macros, and Advanced Features: 7 macros.

Suggested change

#### Format & Case (4 macros)

- `format!` - Format string with interpolation (requires `proc` feature)

- `convert_ascii_case!` - Convert ASCII case

- `convert_case!` - Convert to various cases (requires `case` feature)

- `cstr!` - Create C string literal

#### Advanced Features (8 macros)

- `raw_cstr!` - Create raw C string

#### Format & Case (5 macros)

- `format!` - Format string with interpolation (requires `proc` feature)

- `convert_ascii_case!` - Convert ASCII case

- `convert_case!` - Convert to various cases (requires `case` feature)

- `cstr!` - Create C string literal

- `raw_cstr!` - Create raw C string

#### Advanced Features (7 macros)

+- `cstr!` - Create C string literal
+
+#### Advanced Features (8 macros)
+- `raw_cstr!` - Create raw C string


The heading states "Advanced Features (8 macros)" but only 8 items are listed including raw_cstr! which should be in Format & Case category. After moving raw_cstr! to the correct category, this section should have 7 macros and the heading should be updated accordingly.

Suggested change

#### Format & Case (4 macros)

- `format!` - Format string with interpolation (requires `proc` feature)

- `convert_ascii_case!` - Convert ASCII case
