Expand description
A function signature as seen by type inference: Several parameter types and one return type.

type Result = CallableSig
type Result = CallableSig
The type of value that will be produced once folding is done.
Typically this is Self
, unless Self
contains borrowed
values, in which case owned values are produced (for example,
one can fold over a &T
value where T: Fold
, in which case
you get back a T
, not a &T
). Read more
Apply the given folder folder
to self
; binders
is the
number of binders that are in scope when beginning the
folder. Typically binders
starts as 0, but is adjusted when
we encounter Binders<T>
in the IR or other similar
constructs. Read more

Self: Sized,
fn display<'a>(&'a self, db: &'a dyn HirDatabase) -> HirDisplayWrapper<'a, Self> where

Returns a Display
able type that is human-readable.
Use this for showing types to the user (e.g. diagnostics) Read more

Self: Sized,
fn display_truncated<'a>(
&'a self,
db: &'a dyn HirDatabase,
max_size: Option<usize>
) -> HirDisplayWrapper<'a, Self> where
Self: Sized,
Returns a Display
able type that is human-readable and tries to be succinct.
Use this for showing types to the user where space is constrained (e.g. doc popups) Read more

) -> Result<String, DisplaySourceCodeError>
fn display_source_code<'a>(
&'a self,
db: &'a dyn HirDatabase,
module_id: ModuleId
) -> Result<String, DisplaySourceCodeError>
Returns a String representation of self
that can be inserted into the given module.
Use this when generating code (e.g. assists) Read more

Self: Sized,
Returns a String representation of self

This method tests for self
and other
values to be equal, and is used
by ==
. Read more
