depending on the cast
argument
sourcefn generic_delimiters(

fn generic_delimiters(

Prints <...>
around what f
prints.
sourcefn should_print_region(&self, region: Region<'tcx>) -> bool
fn should_print_region(&self, region: Region<'tcx>) -> bool
Returns true
if the region should be printed in
optional positions, e.g., &'a T
or dyn Tr + 'b
.
This is typically the case for all non-'_
regions. Read more

fn pretty_print_const_pointer<Prov: Provenance>(
self,
p: Pointer<Prov>,
ty: Ty<'tcx>,
print_ty: bool
) -> Result<Self::Const, Self::Error>
This is overridden for MIR printing because we only want to hide alloc ids from users, not from MIR where it is actually useful. Read more

T: Print<'tcx, Self, Output = Self, Error = Self::Error>,
Prints comma-separated elements.
sourcefn try_print_visible_def_path(
self,
def_id: DefId
) -> Result<(Self, bool), Self::Error>
fn try_print_visible_def_path(
self,
def_id: DefId
) -> Result<(Self, bool), Self::Error>
If possible, this returns a global path resolving to def_id
that is visible
from at least one local module, and returns true
. If the crate defining def_id
is
declared with an extern crate
, the path is guaranteed to use the extern crate
. Read more
sourcefn try_print_trimmed_def_path(
self,
def_id: DefId
) -> Result<(Self::Path, bool), Self::Error>
fn try_print_trimmed_def_path(
self,
def_id: DefId
) -> Result<(Self::Path, bool), Self::Error>
Try to see if this path can be trimmed to a unique symbol name.
sourcefn try_print_visible_def_path_recur(
self,
def_id: DefId,
callers: &mut Vec<DefId>
) -> Result<(Self, bool), Self::Error>
fn try_print_visible_def_path_recur(
self,
def_id: DefId,
callers: &mut Vec<DefId>
) -> Result<(Self, bool), Self::Error>
Does the work of try_print_visible_def_path
, building the
full definition path recursively before attempting to
post-process it into the valid and visible version that
accounts for re-exports. Read more
