contains_try 🔒: returns true if expr contains match expr desugared from try
contains_unsafe_block: Checks if the given expression contains an unsafe block
find_all_ret_expressions

for_each_expr_without_closures: Calls the given function once for each expression contained. This does not enter any bodies or nested items.
for_each_local_assignment: Runs the given function for each path expression referencing the given local which occur after the given expression.
for_each_local_use_after_expr: Runs the given function for each path expression referencing the given local which occur after the given expression.
for_each_unconsumed_temporary
for_each_value_source: Runs the given function for each sub-expression producing the final value consumed by the parent of the give expression.
is_const_evaluatable: Checks if the given expression is a constant.
is_expr_unsafe: Checks if the given expression performs an unsafe operation outside of an unsafe block.
is_local_used: Checks if the given local is used.
is_res_used: Checks if the given resolved path is used in the given body.
