Struct Topic

pub struct Topic { /* private fields */ }

An ink! topic.

Implementations

impl Topic

pub fn field(&self) -> Option<&RecordField>

Returns the RecordField item (if any).

Trait Implementations

impl Clone for Topic

fn clone(&self) -> Topic

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Topic

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

Formats the value using the given formatter.

impl InkEntity for Topic

type AST = RecordField

Associated AST node type.

fn can_cast(node: &SyntaxNode) -> bool

Returns true if an ink! entity can be derived from the syntax node.

fn cast(node: SyntaxNode) -> Option<Self>

Returns an ink! entity if one can be derived for the syntax node.

fn syntax(&self) -> &SyntaxNode

Returns the root syntax node for the ink! entity.

fn ast(&self) -> Option<&Self::AST>

Returns the AST node for the ink! entity.

fn ink_attr(&self) -> Option<&InkAttribute>

Returns the ink! attribute the ink! entity was derived from (if any).

fn tree(&self) -> InkTree<'_>

Returns ink! entity tree.

fn item_at_offset(&self, offset: TextSize) -> ItemAtOffset

Returns a representation of a token in the subtree which covers the position.

impl PartialEq for Topic

fn eq(&self, other: &Topic) -> 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.
