Struct Function

pub struct Function { /* private fields */ }

An ink! function.

Implementations

impl Function

pub fn id(&self) -> Option<u16>

Returns the function id (if any).

pub fn function_arg(&self) -> Option<InkArg>

Returns the ink! function argument (if any).

pub fn handle_status_arg(&self) -> Option<InkArg>

Returns the ink! handle_status argument (if any).

Trait Implementations

impl Clone for Function

fn clone(&self) -> Function

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Function

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

Formats the value using the given formatter.

impl InkEntity for Function

type AST = Fn

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 IsChainExtensionFn for Function

const ID_ARG_KIND: InkArgKind = crate::InkArgKind::Function

fn id<T>(&self) -> Option<T>

where T: IsIntId,

Returns the id of the chain extension function (if any).

fn id_arg(&self) -> Option<InkArg>

Returns the chain extension function’s id argument (if any) (i.e. function for ink! v5 and extension for ink! v4).

fn handle_status_arg(&self) -> Option<InkArg>

Returns the ink! handle_status argument (if any).

impl IsInkFn for Function

fn fn_item(&self) -> Option<&Fn>

Returns the fn item (if any).

impl PartialEq for Function

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