Kind of AST item (shared vocabulary across crates).

This enum represents the type of an AST item and is used for:

• Item-level conflict detection in parallel execution
• Intent extraction and pattern matching
• Spec directives and documentation

Design

• Top-level items: items that can appear at module level
• Nested items: items that appear inside other items (methods in impl, fields in struct)
• Wildcard: for pattern matching any kind

Variants

Function

Function definition (fn foo() {})

Struct

Struct definition (struct Foo {})

Enum

Enum definition (enum Foo {})

Trait

Trait definition (trait Foo {})

Impl

Impl block (impl Foo {} or impl Trait for Foo {})

TypeAlias

Type alias (type Foo = Bar;)

Const

Const item (const FOO: i32 = 1;)

Static

Static item (static FOO: i32 = 1;)

Mod

Module (mod foo; or mod foo {})

Use

Use statement (use std::io;)

Macro

Macro invocation at item level (macro_rules! or foo!())

Method

Method inside an impl or trait block

Field

Field in a struct or enum variant

Variant

Variant in an enum

LocalVar

Local variable (let x = ...)

Parameter

Function parameter

TupleField

Tuple struct/enum field (indexed by number: 0, 1, 2…)

Any

Wildcard - matches any kind (for pattern matching)

Other

Unknown or unsupported item

Implementations

impl ItemKind

pub fn as_str(&self) -> &'static str

Returns the string representation of this kind.

pub fn is_top_level(&self) -> bool

Returns true if this is a top-level item (can appear at module level).

pub fn is_nested(&self) -> bool

Returns true if this is a nested item (appears inside another item).

pub fn is_variable(&self) -> bool

Returns true if this is a variable-level item (local scope).

pub fn matches(&self, other: &ItemKind) -> bool

Returns true if this matches the given kind (considering Any as wildcard).

Trait Implementations

impl Clone for ItemKind

fn clone(&self) -> ItemKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ItemKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ItemKind

fn deserialize<__D>( __deserializer: __D, ) -> Result<ItemKind, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ItemKind

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

Formats the value using the given formatter.

impl From<&PureItem> for ItemKind

fn from(item: &PureItem) -> ItemKind

Converts to this type from the input type.

impl From<PureSymbolKind> for ItemKind

fn from(kind: PureSymbolKind) -> ItemKind

Converts to this type from the input type.

impl Hash for ItemKind

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 PartialEq for ItemKind

fn eq(&self, other: &ItemKind) -> 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 Serialize for ItemKind

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ItemKind

impl Eq for ItemKind
