sourcefn should_print_region(&self, _region: Region<'_>) -> bool
fn should_print_region(&self, _region: Region<'_>) -> 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 moresourcefn comma_sep<T>(

fn comma_sep<T>(
self,
elems: impl Iterator<Item = T>
) -> Result<Self, Self::Error>where
T: Print<'tcx, Self, Output = Self, Error = Self::Error>,
Prints comma-separated elements.

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 moresourcefn try_print_trimmed_def_path(

fn try_print_trimmed_def_path(

def_id: DefId
) -> Result<(Self::Path, bool), Self::Error>
Try to see if this path can be trimmed to a unique symbol name.

fn try_print_visible_def_path_recur(

def_id: DefId,
callers: &mut Vec<DefId, Global>
) -> 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 morefn pretty_path_qualified(
