babbel_yaml 0.1.0

// =====================================================================================
//  File: anchor_tests.rs
//  Location: library/src/internal_tests/
// -------------------------------------------------------------------------------------
//  Purpose:
//      Internal tests for YAML anchor and alias handling in the babbel_yaml crate.
//      These tests validate correct parsing and behavior of YAML anchors, aliases,
//      and related edge cases, including anchor names with special characters,
//      empty anchor values, and anchors on various node types.
//
//  Context:
//      - Part of the babbel_yaml project, a Rust YAML parser/serializer.
//      - Tests are based on YAML specification examples and custom edge cases.
//      - Ensures compliance with YAML anchor/alias semantics and robustness.
//
// -------------------------------------------------------------------------------------
//  Test Coverage:
//      - Anchor names with special characters (e.g., colon)
//      - Empty anchor values
//      - Anchors on sequences and mappings
//      - Alias resolution
//      - Panic safety for malformed anchors/aliases
// =====================================================================================
