Struct hir::Static

pub struct Static { /* private fields */ }

Implementations

impl Static

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

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

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

pub fn value(self, db: &dyn HirDatabase) -> Option<Expr>

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

pub fn eval(self, db: &dyn HirDatabase) -> Result<String, ConstEvalError>

Evaluate the static and return the result as a string.

This function is intended for IDE assistance, different from Static::render_eval.

pub fn render_eval( self, db: &dyn HirDatabase, edition: Edition, ) -> Result<String, ConstEvalError>

Evaluate the static and return the result as a string, with more detailed information.

This function is intended for user-facing display.

Trait Implementations

impl AsExternAssocItem for Static

fn as_extern_assoc_item(self, db: &dyn HirDatabase) -> Option<ExternAssocItem>

impl Clone for Static

fn clone(&self) -> Static

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Static

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

Formats the value using the given formatter.

impl From<Static> for DefWithBody

fn from(it: Static) -> DefWithBody

Converts to this type from the input type.

impl From<Static> for ModuleDef

fn from(it: Static) -> ModuleDef

Converts to this type from the input type.

impl From<Static> for StaticId

fn from(ty: Static) -> StaticId

Converts to this type from the input type.

impl From<StaticId> for Static

fn from(id: StaticId) -> Static

Converts to this type from the input type.

impl HasAttrs for Static

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

impl HasContainer for Static

fn container(&self, db: &dyn HirDatabase) -> ItemContainer

impl HasCrate for Static

fn krate(&self, db: &dyn HirDatabase) -> Crate

impl HasSource for Static

type Ast = Static

fn source(self, db: &dyn HirDatabase) -> Option<InFile<Self::Ast>>

Fetches the definition’s source node. Using [crate::Semantics::source] is preferred when working with crate::Semantics, as that caches the parsed file in the semantics’ cache.

impl HasVisibility for Static

fn visibility(&self, db: &dyn HirDatabase) -> Visibility

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

impl Hash for Static

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 Static

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 Static

fn eq(&self, other: &Static) -> 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 StructuralPartialEq for Static
