Struct TypeParam

pub struct TypeParam { /* private fields */ }

Implementations

impl TypeParam

pub fn merge(self) -> TypeOrConstParam

pub fn name(self, db: &dyn HirDatabase) -> Name

pub fn module(self, db: &dyn HirDatabase) -> Module

pub fn is_implicit(self, db: &dyn HirDatabase) -> bool

Is this type parameter implicitly introduced (eg. Self in a trait or an impl Trait argument)?

pub fn ty(self, db: &dyn HirDatabase) -> Type

pub fn trait_bounds(self, db: &dyn HirDatabase) -> Vec<Trait>

FIXME: this only lists trait bounds from the item defining the type parameter, not additional bounds that might be added e.g. by a method if the parameter comes from an impl!

pub fn default(self, db: &dyn HirDatabase) -> Option<Type>

pub fn is_unstable(self, db: &dyn HirDatabase) -> bool

Trait Implementations

impl Clone for TypeParam

fn clone(&self) -> TypeParam

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TypeParam

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

Formats the value using the given formatter.

impl From<TypeParam> for GenericParam

fn from(it: TypeParam) -> GenericParam

Converts to this type from the input type.

impl From<TypeParam> for TypeParamId

fn from(ty: TypeParam) -> TypeParamId

Converts to this type from the input type.

impl From<TypeParamId> for TypeParam

fn from(id: TypeParamId) -> TypeParam

Converts to this type from the input type.

impl HasAttrs for TypeParam

fn attrs(self, db: &dyn HirDatabase) -> AttrsWithOwner

impl Hash for TypeParam

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl HirDisplay for TypeParam

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

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

where Self: Sized,

Returns a Displayable type that is human-readable.

fn display<'a>( &'a self, db: &'a dyn HirDatabase, edition: Edition, ) -> 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>, edition: Edition, ) -> 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_limited<'a>( &'a self, db: &'a dyn HirDatabase, limited_size: Option<usize>, edition: Edition, ) -> HirDisplayWrapper<'a, Self>

where Self: Sized,

Returns a Displayable type that is human-readable and tries to limit the number of items inside. Use this for showing definitions which may contain too many items, like trait, struct, enum

fn display_source_code<'a>( &'a self, db: &'a dyn HirDatabase, module_id: ModuleId, allow_opaque: bool, ) -> 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

fn display_with_container_bounds<'a>( &'a self, db: &'a dyn HirDatabase, show_container_bounds: bool, edition: Edition, ) -> HirDisplayWrapper<'a, Self>

where Self: Sized,

Returns a String representation of self that shows the constraint from the container for functions

impl PartialEq for TypeParam

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
