InferenceVar(InferenceVar)

Lifetime whose value is being inferred.

Placeholder(PlaceholderIndex)

Lifetime on some yet-unknown placeholder.

Static

Error

A lifetime that resulted from some error

Implementations

impl<I> LifetimeData<I>

where I: Interner,

pub fn intern(self, interner: I) -> Lifetime<I>

Wrap the lifetime data in a lifetime.

Trait Implementations

impl HirDisplay for LifetimeData

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, display_kind: DisplayKind, 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, display_target: DisplayTarget, ) -> 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>, display_target: DisplayTarget, ) -> 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>, display_target: DisplayTarget, ) -> 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, display_target: DisplayTarget, ) -> 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, display_target: DisplayTarget, ) -> HirDisplayWrapper<'a, Self>

where Self: Sized,

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

impl<I> CastTo<LifetimeData<I>> for LifetimeData<I>

where I: Interner,

fn cast_to( self, _interner: <LifetimeData<I> as HasInterner>::Interner, ) -> LifetimeData<I>

Cast a value to type T.

impl<I> Clone for LifetimeData<I>

where I: Clone + Interner,

fn clone(&self) -> LifetimeData<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I> Debug for LifetimeData<I>

where I: Interner,

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

Formats the value using the given formatter.

impl<I> HasInterner for LifetimeData<I>

where I: Interner,

type Interner = I

The interner associated with the type.

impl<I> Hash for LifetimeData<I>

where I: Hash + Interner,

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

where __H: Hasher,

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<I> Ord for LifetimeData<I>

where I: Ord + Interner,

fn cmp(&self, other: &LifetimeData<I>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<I> PartialEq for LifetimeData<I>

where I: PartialEq + Interner,

fn eq(&self, other: &LifetimeData<I>) -> 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.

impl<I> PartialOrd for LifetimeData<I>

where I: PartialOrd + Interner,

fn partial_cmp(&self, other: &LifetimeData<I>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests greater than (for self and other) and is used by the > operator.
