Enum DeclNode 

pub enum DeclNode {
    FunctionDefinition(FunctionDefinition),
    VariableDeclaration(VariableDeclaration),
    ContractDefinition(ContractDefinition),
    EventDefinition(EventDefinition),
    ErrorDefinition(ErrorDefinition),
    StructDefinition(StructDefinition),
    EnumDefinition(EnumDefinition),
    ModifierDefinition(ModifierDefinition),
    UserDefinedValueTypeDefinition(UserDefinedValueTypeDefinition),
}

A reference to any declaration-level AST node.

This enum covers the node types that hover, goto, and references care about: functions, variables, contracts, events, errors, structs, enums, modifiers, and user-defined value types.

Built by extract_decl_nodes and stored in CachedBuild for O(1) typed node lookup by ID.

Implementations

impl DeclNode

pub fn id(&self) -> NodeID

Node ID of the declaration.

pub fn name(&self) -> &str

Name of the declaration.

pub fn src(&self) -> &str

Source location string ("offset:length:fileId").

pub fn scope(&self) -> Option<NodeID>

Scope (parent) node ID, if available.

pub fn base_functions(&self) -> Option<&[NodeID]>

Base functions/modifiers this declaration overrides.

Returns IDs of interface/abstract declarations that this function or modifier implements or overrides.

pub fn documentation(&self) -> Option<&Documentation>

Documentation attached to the declaration.

pub fn selector(&self) -> Option<&str>

Function selector (4-byte hex for functions/errors, 32-byte for events).

pub fn extract_typed_selector(&self) -> Option<Selector>

Extract a typed [Selector] from this declaration.

Returns Selector::Func for functions, public variables, and errors, or Selector::Event for events. Equivalent to extract_selector(&Value).

pub fn extract_doc_text(&self) -> Option<String>

Extract documentation text from this declaration.

Returns the NatSpec text string, equivalent to the raw extract_documentation().

pub fn build_signature(&self) -> Option<String>

Build a Solidity-style signature string for this declaration.

Typed equivalent of build_function_signature(&Value) in hover.rs. Uses direct field access instead of .get("field").and_then(|v| v.as_str()) chains.

pub fn param_strings(&self) -> Vec<String>

Build individual parameter strings for signature help.

Returns a vec of strings like ["uint256 amount", "uint16 tax"]. Typed equivalent of build_parameter_strings(&Value) in hover.rs.

pub fn parameters(&self) -> Option<&ParameterList>

Returns the ParameterList for this declaration’s parameters, if any.

pub fn return_parameters(&self) -> Option<&ParameterList>

Returns the ParameterList for this declaration’s return parameters, if any.

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

Returns the node type string, matching the JSON nodeType field.

pub fn type_string(&self) -> Option<&str>

Returns the type description string for this declaration, if available.

pub fn param_names(&self) -> Option<Vec<String>>

Returns parameter/member names for inlay hint resolution.

For functions, events, errors, modifiers: returns parameters.parameters[].name. For structs: returns members[].name. Typed equivalent of get_parameter_names(&Value) in inlay_hints.rs.

pub fn is_constructor(&self) -> bool

For constructors, returns true if this is a constructor function.

Trait Implementations

impl Clone for DeclNode

fn clone(&self) -> DeclNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeclNode

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

Formats the value using the given formatter.
