fn print_value_path( self, def_id: DefId, args: &'tcx [GenericArg<'tcx>] ) -> Result<Self::Path, Self::Error>
Like
print_def_path
but for value paths.fn in_binder<T>(self, value: &Binder<'tcx, T>) -> Result<Self, Self::Error>where T: Print<'tcx, Self, Output = Self, Error = Self::Error> + TypeFoldable<TyCtxt<'tcx>>,

fn typed_value( self, f: impl FnOnce(Self) -> Result<Self, Self::Error>, t: impl FnOnce(Self) -> Result<Self, Self::Error>, conversion: &str ) -> Result<Self::Const, Self::Error>
Prints
{f: t}
or {f as t}
depending on the cast
argumentsource§fn generic_delimiters(
self,
f: impl FnOnce(Self) -> Result<Self, Self::Error>
) -> Result<Self, Self::Error>
fn generic_delimiters( self, f: impl FnOnce(Self) -> Result<Self, Self::Error> ) -> Result<Self, Self::Error>
Prints
<...>
around what f
prints.source§fn 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.source§fn pretty_print_const_pointer<Prov: Provenance>(
self,
p: Pointer<Prov>,
ty: Ty<'tcx>
) -> Result<Self::Const, Self::Error>
fn pretty_print_const_pointer<Prov: Provenance>( self, p: Pointer<Prov>, ty: Ty<'tcx> ) -> 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.

self,
elems: impl Iterator<Item = T>
) -> Result<Self, Self::Error>where

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

source§fn 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.

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 morefn pretty_path_qualified( self, self_ty: Ty<'tcx>, trait_ref: Option<TraitRef<'tcx>> ) -> Result<Self::Path, Self::Error>

Insert the trait ref and optionally a projection type associated with it into either the
traits map or fn_traits map, depending on if the trait is in the Fn* family of traits.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
