# `obiutils` Package Overview
|
|||
|
|
|
|||
|
|
This Go package provides utility functions for common data conversion, serialization, and reflection tasks.
|
|||
|
|
|
|||
|
|
- **Custom Error Types**: Defines typed errors (`NotAnInteger`, `NotAFloat64`, etc.) for precise type validation failures.
|
|||
|
|
- **Interface-to-Type Casting**: Offers robust conversion functions:
|
|||
|
|
- `InterfaceToFloat64Map`, `InterfaceToIntSlice`, etc., handling nested interfaces and type coercion (e.g. `int` → `float64`, slices of `interface{}`).
|
|||
|
|
- **File I/O**: `ReadLines` reads a file line-by-line into a string slice, handling buffered reading efficiently.
|
|||
|
|
- **Concurrency**: `AtomicCounter` returns an incrementing integer generator—thread-safe via mutex, optionally starting from a given value.
|
|||
|
|
- **JSON Serialization**: `JsonMarshal` and `JsonMarshalByteBuffer` provide UTF‑8–preserving JSON encoding (avoids Go’s default HTML escaping).
|
|||
|
|
- **Reflection Helpers**:
|
|||
|
|
- `IsAMap`, `IsASlice`, `IsAnArray` detect container types.
|
|||
|
|
- `HasLength`, `Len`, and `IsAContainer` abstract length operations across maps, slices, arrays, or custom types with a `.Len()` method.
|
|||
|
|
- **Deep Copying**: `MustFillMap` performs deep copying of nested structures using `go-deepcopy`.
|
|||
|
|
|
|||
|
|
All functions prioritize safety, type correctness, and usability in data-heavy or concurrent applications.
