[`T-AST`] issues will generally need you to match against a predefined syntax structure. To figure out how this syntax structure is encoded in the AST, it is recommended to run -`rustc -Z ast-json` on an example of the structure and compare with the [nodes in the AST docs]. +`rustc -Z unpretty=ast-tree` on an example of the structure and compare with the [nodes in the AST docs]. Usually the lint will end up to be a nested series of matches and ifs, [like so][deep-nesting]. But we can make it nest-less by using [if_chain] macro, [like this][nest-less]. |
