This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig standard library. Private Struct

LocalPtr

Doc Source

Private Struct

std.zig.AstGen.Scope.LocalPtr

const LocalPtr = struct

This could be a const or var local. It has a pointer instead of a value. This structure lives as long as the AST generation of the Block node that contains the variable.

Fields

base: Scope = Scope{ .tag = base_tag }
parent: *Scope: Parents can be: LocalVal, LocalPtr, GenZir, Defer, Namespace.
gen_zir: *GenZir
ptr: Zir.Inst.Ref
token_src: Ast.TokenIndex: Source location of the corresponding variable declaration.
used: Ast.OptionalTokenIndex = .none: Track the first identifier where it is referenced. .none means never referenced.
discarded: Ast.OptionalTokenIndex = .none: Track the identifier where it is discarded, like this _ = foo;. .none means never discarded.
used_as_lvalue: bool = false: Whether this value is used as an lvalue after initialization. If not, we know it can be const, so will emit a compile error if it is var.
name: Zir.NullTerminatedString: String table index.
id_cat: IdCat
maybe_comptime: bool: true means we find out during Sema whether the value is comptime. false means it is already known at AstGen the value is runtime-known.
