Functions

expr_block	Like snippet_block, but add braces if the expr is not an ExprBlock Also takes an Option which can be put inside the braces
get_item_name	get the name of the item the expression is in, if available
get_parent_expr	get a parent expr if any – this is useful to constrain a lint
in_external_macro	returns true if the macro that expanded the crate was outside of the current crate or was a compiler plugin
in_macro	returns true this expn_info was expanded by any macro
is_from_for_desugar	checks if a let decl is from a for loop desugaring
is_integer_literal
match_def_path	check if a DefId's path matches the given absolute type path usage e.g. with match_def_path(cx, id, &["core", "option", "Option"])
match_path	match a Path against a slice of segment string literals, e.g. match_path(path, &["std", "rt", "begin_unwind"])
match_path_ast	match a Path against a slice of segment string literals, e.g. match_path(path, &["std", "rt", "begin_unwind"])
match_trait_method	check if method call given in "expr" belongs to given trait
match_type	check if type is struct or enum type with given def path
snippet	convert a span to a code snippet if available, otherwise use default, e.g. snippet(cx, expr.span, "..")
snippet_block	convert a span (from a block) to a code snippet if available, otherwise use default, e.g. snippet(cx, expr.span, "..") This trims the code of indentation, except for the first line Use it for blocks or block-like things which need to be printed as such
span_help_and_lint
span_lint
span_note_and_lint
trim_multiline	Trim indentation from a multiline string with possibility of ignoring the first line
walk_ptrs_ty	return the base type for references and raw pointers
walk_ptrs_ty_depth	return the base type for references and raw pointers, and count reference depth
