Enum StructItem 

pub enum StructItem<N: TreeNode = SyntaxNode> {
    Member(UnboundDecl<N>),
    Metadata(MetadataSection<N>),
    ParameterMetadata(ParameterMetadataSection<N>),
}

Represents an item in a struct definition.

Variants

Member(UnboundDecl<N>)

The item is a member declaration.

Metadata(MetadataSection<N>)

The item is a metadata section.

ParameterMetadata(ParameterMetadataSection<N>)

The item is a parameter meta section.

Implementations

impl<N: TreeNode> StructItem<N>

pub fn can_cast(kind: SyntaxKind) -> bool

Returns whether or not the given syntax kind can be cast to StructItem.

pub fn cast(inner: N) -> Option<Self>

Casts the given node to StructItem.

Returns None if the node cannot be cast.

pub fn inner(&self) -> &N

Gets a reference to the inner node.

pub fn as_unbound_decl(&self) -> Option<&UnboundDecl<N>>

Attempts to get a reference to the inner UnboundDecl.

• If self is a StructItem::Member, then a reference to the inner UnboundDecl is returned wrapped in Some.
• Else, None is returned.

pub fn into_unbound_decl(self) -> Option<UnboundDecl<N>>

Consumes self and attempts to return the inner UnboundDecl.

• If self is a StructItem::Member, then the inner UnboundDecl is returned wrapped in Some.
• Else, None is returned.

pub fn as_metadata_section(&self) -> Option<&MetadataSection<N>>

Attempts to get a reference to the inner MetadataSection.

• If self is a StructItem::Metadata, then a reference to the inner MetadataSection is returned wrapped in Some.
• Else, None is returned.

pub fn into_metadata_section(self) -> Option<MetadataSection<N>>

Consumes self and attempts to return the inner MetadataSection.

• If self is a StructItem::Metadata, then the inner MetadataSection is returned wrapped in Some.
• Else, None is returned.

pub fn as_parameter_metadata_section( &self, ) -> Option<&ParameterMetadataSection<N>>

Attempts to get a reference to the inner ParameterMetadataSection.

• If self is a StructItem::ParameterMetadata, then a reference to the inner ParameterMetadataSection is returned wrapped in Some.
• Else, None is returned.

pub fn into_parameter_metadata_section( self, ) -> Option<ParameterMetadataSection<N>>

Consumes self and attempts to return the inner ParameterMetadataSection.

• If self is a StructItem::ParameterMetadata, then the inner ParameterMetadataSection is returned wrapped in Some.
• Else, None is returned.

pub fn child(node: &N) -> Option<Self>

Finds the first child that can be cast to a StructItem.

pub fn children(node: &N) -> impl Iterator<Item = Self> + use<'_, N>

Finds all children that can be cast to a StructItem.

Trait Implementations

impl<N: Clone + TreeNode> Clone for StructItem<N>

fn clone(&self) -> StructItem<N>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<N: Debug + TreeNode> Debug for StructItem<N>

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

Formats the value using the given formatter.

impl<N: PartialEq + TreeNode> PartialEq for StructItem<N>

fn eq(&self, other: &StructItem<N>) -> 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.
