Module syntax::ast_utilUnstable

Structs

IdRange
IdVisitor	A visitor that applies its operation to all of the node IDs in a visitable thing.

Constants

AS_PREC

Precedence of the as operator, which is a binary operator not appearing in the prior table.

Traits

IdVisitingOperation
PostExpansionMethod	Macro invocations are guaranteed not to occur after expansion is complete. Extracting fields of a method requires a dynamic check to make sure that it's not a macro invocation. This check is guaranteed to succeed, assuming that the invocations are indeed gone.

Functions

binop_to_string
compute_id_range_for_fn_body	Computes the id range for a single fn body, ignoring nested items.
compute_id_range_for_inlined_item
empty_generics
float_ty_to_string
ident_to_pat
ident_to_path
impl_pretty_name	Generate a "pretty" name for an impl from its type and trait. This is designed so that symbols of impl'd methods give some hint of where they came from, (previously they would all just be listed as __extensions__::method_name::hash, with no indication of the type).
int_ty_max
int_ty_to_string	Get a string representation of a signed int type, with its value. We want to avoid "45int" and "-3int" in favor of "45" and "-3"
is_by_value_binop	Returns true if the binary operator takes its arguments by value
is_by_value_unop	Returns true if the unary operator takes its argument by value
is_comparison_binop
is_local
is_path
is_shift_binop
is_symmetric_binop	Returns true if the binary operator is symmetric in the sense that LHS and RHS must have the same type. So the type of LHS can serve as an hint for the type of RHS and vice versa.
lazy_binop
lit_is_str	Returns true if this literal is a string and false otherwise.
local_def
name_to_dummy_lifetime
operator_prec	Maps a binary operator to its precedence
pat_is_ident	Returns true if the given pattern consists solely of an identifier and false otherwise.
path_name_eq
path_name_i
path_to_ident
segments_name_eq
split_trait_methods
stmt_id
struct_def_is_tuple_like	Returns true if the given struct def is tuple-like; i.e. that its fields are unnamed.
struct_field_visibility
trait_item_to_ty_method	extract a TypeMethod from a TraitItem. if the TraitItem is a default, pull out the useful fields to make a TypeMethod
trait_method_to_ty_method
uint_ty_max
uint_ty_to_string	Get a string representation of an unsigned int type, with its value. We want to avoid "42u" in favor of "42us". "42uint" is right out.
unop_to_string
visit_ids_for_inlined_item
walk_pat
