Overview

Drop-in Rust reimplementation of RSpec/VariableDefinition (rubocop-rspec 3.10.2).

Rust classifies once on the shared walk: the candidate matcher and the top-level-spec-group gate are exactly RSpec/VariableName's (a send-shaped let/subject with a literal first argument inside a top-level spec group). The EnforcedStyle decides the offenders: symbols (default) flags plain str names, strings flags sym AND dsym names; a dstr name is never flagged (probed). Rust already applies the style, so the wire carries only real offenders.

The wrapper reproduces stock's correct_variable: a sym becomes value.inspect (variable.value.to_s.inspect), a str becomes value.to_sym.inspect, and a dsym becomes its source minus the leading colon (variable.source[1..]).
