chore(deps)(deps): update convert_case requirement from 0.11 to 0.12

[dependabot]

Updates the requirements on convert_case to permit the latest version.

Changelog

Sourced from convert_case's changelog.

0.12.0: Optimizations

This release improves speed and memory efficiency. A couple techniques were used:

• Character case checks first check ascii before doing the more expensive grapheme checks (which require heap allocations).
• Delimiter only splits get a dedicated path in the split method.
• The case of characters is computed upfront in a bitmask before checking individual boundary conditions in split. Built-in boundaries get a custom implementation built on top of this bitmask.

0.11.0: Multiple Patterns

The headline change permits trailing, leading, and duplicate delimiters to persist (default) or be removed. Instead of applying a single pattern, Converter supports multiple patterns and will apply them in order. This comes with another pattern Pattern::RemoveEmpty that drops empty words. This allows for opting into what was default behavior in 0.8.0 and before.

New features:

• Converter now supports multiple patterns via Converter.patterns: Vec<Pattern>. Patterns are applied in sequence, allowing for composition.
• Pattern::RemoveEmpty filters out empty words. This is useful when splitting produces empty words from leading, trailing, or duplicate delimiters (e.g., "--a--b" split on hyphens).
• Casing::remove_empty() is a convenience method that adds Pattern::RemoveEmpty to the patterns vector.

"--leading-delims".remove_empty().to_case(Case::Camel)
// "leadingDelims"

Breaking changes:

• delim_boundary macro is now separator
• Removed Casing::is_case. Similar functionality is now implemented in convert-case-extras.
• Instances of delim have been renamed to delimiter:
  • Converter.delim -> Converter.delimiter
  • Converter::set_delim -> Converter::set_delimiter
  • Case::Custom.delim -> Case::Custom.delimiter
  • Case::delim -> Case::delimiter
• Converter.pattern is now Converter.patterns with type Vec<Pattern>
  • New pattern methods on Converter just like boundaries: set_patterns, add_pattern, add_patterns, remove_pattern, remove_patterns.
  • Pattern::Noop removed. An empty patterns vector represents no mutation.
• Boundary::Custom and Pattern::Custom variants are no longer comparable.
  • Implementations of PartialEq, Eq, and Hash are no longer derived on Boundary and Pattern, and have been manually implemented.
  • Custom variants always return false for equality checks because function pointers cannot be reliably compared. This has been true for all of rust, but the compiler warning is relatively new to the author. This means remove_boundary and remove_pattern will not work for custom variants.
  • Further, all Custom variants now hash to the same value.

Other changes:

• Much improved documentation: fixed typos, better examples.
