Trait Implementations

impl Clone for CallableSig

fn clone(&self) -> CallableSig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CallableSig

Formats the value using the given formatter.

impl Eq for CallableSig

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 !=.

fn walk_mut_binders(
    &mut self,
    f: &mut impl FnMut(&mut Ty, DebruijnIndex),
    binders: DebruijnIndex
)

Walk the type, counting entered binders.

) -> Self where
    Self: Sized, 

fn fold(self, f: &mut impl FnMut(Ty) -> Ty) -> Self where
    Self: Sized, 

fn subst_bound_vars(self, substs: &Substitution) -> Self where
    Self: Sized,

    self,
    substs: &Substitution,
    depth: DebruijnIndex
) -> Self where
    Self: Sized, 

Substitutes TyKind::Bound vars with the given substitution.

fn shift_bound_vars(self, n: DebruijnIndex) -> Self where
    Self: Sized, 

Shifts up debruijn indices of TyKind::Bound vars by n.

fn shift_bound_vars_out(self, n: DebruijnIndex) -> Self where
    Self: Sized + Debug, 

Shifts debruijn indices of TyKind::Bound vars out (down) by n.
