Struct ra_ap_hir_ty::CallableSig

pub struct CallableSig { /* fields omitted */ }

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

Implementations

impl CallableSig

pub fn from_params_and_return(
    params: Vec<Ty>,
    ret: Ty,
    is_varargs: bool
) -> CallableSig

pub fn from_fn_ptr(fn_ptr: &FnPointer) -> CallableSig

pub fn to_fn_ptr(&self) -> FnPointer

pub fn params(&self) -> &[Ty]

pub fn ret(&self) -> &Ty

Trait Implementations

impl Clone for CallableSig

fn clone(&self) -> CallableSig

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CallableSig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Fold<Interner> for 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).

fn fold_with<'i>(
    self,
    folder: &mut dyn Folder<'i, Interner>,
    outer_binder: DebruijnIndex
) -> Fallible<Self::Result> where
    Interner: 'i, 

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.

impl HasInterner for CallableSig

type Interner = Interner

The interner associated with the type.

impl HirDisplay for CallableSig

fn hir_fmt(&self, f: &mut HirFormatter<'_>) -> Result<(), HirDisplayError>

fn into_displayable<'a>(
    &'a self,
    db: &'a dyn HirDatabase,
    max_size: Option<usize>,
    omit_verbose_types: bool,
    display_target: DisplayTarget
) -> HirDisplayWrapper<'a, Self> where
    Self: Sized, 

Returns a Displayable type that is human-readable.

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

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

fn display_truncated<'a>(
    &'a self,
    db: &'a dyn HirDatabase,
    max_size: Option<usize>
) -> HirDisplayWrapper<'a, Self> where
    Self: Sized, 

Returns a Displayable 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)

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)

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

Returns a String representation of self for test purposes

impl PartialEq<CallableSig> for CallableSig

fn eq(&self, other: &CallableSig) -> bool

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

fn ne(&self, other: &CallableSig) -> bool

This method tests for !=.

impl TypeWalk for CallableSig

fn walk(&self, f: &mut impl FnMut(&Ty))

impl Eq for CallableSig

impl StructuralEq for CallableSig
