Overview

Drop-in Rust reimplementation of ‘Style/RedundantSelf`.

Rust walks the AST, tracks local-variable scopes and reports the ‘self` receiver of redundant `self.foo` sends, returning the byte range of `self` plus the `.` operator so Ruby can remove both. Offenses come from the per-file bundled run (`Shirobai::Dispatch`); the allow-list is a load-time constant, so this cop is always bundle-eligible.

MSG = 
"Redundant `self` detected."
KERNEL_METHODS =

Same timing as stock (‘KERNEL_METHODS = Kernel.methods(false)`): snapshot once at load, not per investigation.

Kernel.methods(false).map(&:to_s).freeze
