Summary of Changes
Hello @ReneWerner87, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request extends the existing parsing utilities by introducing dedicated functions for int16 and uint16 types. The change aims to provide more specific and potentially optimized parsing capabilities for these integer sizes, accompanied by thorough testing and performance benchmarks to validate their functionality and efficiency.
Highlights
- New Parsing Functions: I've added two new helper functions,
ParseInt16andParseUint16, to theparse.gofile. These functions allow for parsing decimal ASCII strings or byte slices directly intoint16anduint16types, respectively, leveraging existing generic parsing logic. - Comprehensive Testing: I've included new unit tests (
Test_ParseInt16andTest_ParseUint16) inparse_test.goto ensure the correctness of the new parsing functions across various valid and invalid inputs, including boundary conditions and overflow/underflow scenarios. - Performance Benchmarking: I've also added benchmarks (
Benchmark_ParseInt16andBenchmark_ParseUint16) to compare the performance of the new parsing functions (both string and byte slice inputs) against the standard library'sstrconv.ParseIntandstrconv.ParseUintforint16anduint16types.

Code Review
This pull request introduces ParseInt16 and ParseUint16 helper functions, complete with tests and benchmarks. The implementation is sound and aligns with the existing code style. I've provided a couple of suggestions to refactor the new tests using sub-tests, which will enhance maintainability and make test failure reports more informative.
| for _, tt := range tests { | ||
| v, ok := ParseInt16(tt.in) | ||
| require.Equal(t, tt.success, ok) | ||
| if ok { | ||
| require.Equal(t, tt.val, v) | ||
| } | ||
| bts, ok := ParseInt16([]byte(tt.in)) | ||

For better test readability and more granular test failure reporting, consider refactoring the test loop to use sub-tests with t.Run. This will separate the string and []byte test cases, and the test name will clearly indicate which input failed.
This is a common Go testing practice that improves maintainability.
for _, tt := range tests {
t.Run(tt.in, func(t *testing.T) {
t.Run("string", func(t *testing.T) {
v, ok := ParseInt16(tt.in)
require.Equal(t, tt.success, ok)
if ok {
require.Equal(t, tt.val, v)
}
})
t.Run("bytes", func(t *testing.T) {
bts, ok := ParseInt16([]byte(tt.in))
require.Equal(t, tt.success, ok)
if ok {
require.Equal(t, tt.val, bts)
}
})
})

Similar to the Test_ParseInt16 test, this test can be improved by using sub-tests with t.Run. This will make test failures more descriptive and improve the overall structure of the test by separating the string and []byte test cases.
This is a common Go testing practice that improves maintainability.
for _, tt := range tests {
t.Run(tt.in, func(t *testing.T) {
t.Run("string", func(t *testing.T) {
v, ok := ParseUint16(tt.in)
require.Equal(t, tt.success, ok)
if ok {
require.Equal(t, tt.val, v)
}
})
t.Run("bytes", func(t *testing.T) {
bts, ok := ParseUint16([]byte(tt.in))
require.Equal(t, tt.success, ok)
if ok {
require.Equal(t, tt.val, bts)
}
})
})

We should invalid cases here like text, empty string, and nil
