Completion cache built from the AST.

Fields

names: Vec<CompletionItem>

All named identifiers as completion items (flat, unscoped).

name_to_type: HashMap<String, String>

name → typeIdentifier (for dot-completion: look up what type a variable is).

node_members: HashMap<u64, Vec<CompletionItem>>

node id → Vec (members of structs, contracts, enums, libraries).

type_to_node: HashMap<String, u64>

typeIdentifier → node id (resolve a type string to its definition).

name_to_node_id: HashMap<String, u64>

contract/library/interface name → node id (for direct name dot-completion like FullMath.).

method_identifiers: HashMap<u64, Vec<CompletionItem>>

node id → Vec from methodIdentifiers in .contracts section. Full function signatures with 4-byte selectors for contracts/interfaces.

function_return_types: HashMap<(u64, String), String>

(contract_node_id, fn_name) → return typeIdentifier. For resolving foo(). — look up what foo returns.

using_for: HashMap<String, Vec<CompletionItem>>

typeIdentifier → Vec from UsingForDirective. Library functions available on a type via using X for Y.

using_for_wildcard: Vec<CompletionItem>

Wildcard using-for: using X for * — available on all types.

general_completions: Vec<CompletionItem>

Pre-built general completions (AST names + keywords + globals + units). Built once, returned by reference on every non-dot completion request.

scope_declarations: HashMap<u64, Vec<ScopedDeclaration>>

scope node_id → declarations in that scope. Each scope (Block, FunctionDefinition, ContractDefinition, SourceUnit) has the variables/functions/types declared directly within it.

scope_parent: HashMap<u64, u64>

node_id → parent scope node_id. Walk this chain upward to widen the search scope.

scope_ranges: Vec<ScopeRange>

All scope ranges, for finding which scope a byte position falls in. Sorted by span size ascending (smallest first) for efficient innermost-scope lookup.

path_to_file_id: HashMap<String, u64>

absolute file path → AST source file id. Used to map a URI to the file_id needed for scope resolution.

linearized_base_contracts: HashMap<u64, Vec<u64>>

contract node_id → linearized base contracts (C3 linearization order). First element is the contract itself, followed by parents in resolution order. Used to search inherited state variables and functions during scope resolution.
