structstd.builtin.Type.StructField[src]

This data structure is used by the Zig language code generation and therefore must be kept in sync with the compiler implementation.

Fields

name: [:0]const u8
type: type
default_value_ptr: ?*const anyopaque

The type of the default value is the type of this struct field, which is the value of the type field in this struct. However there is no way to refer to that type here, so we use *const anyopaque. See also: defaultValue.

is_comptime: bool
alignment: comptime_int

Functions

FunctiondefaultValue[src]

pub inline fn defaultValue(comptime sf: StructField) ?sf.type

Loads the field's default value from default_value_ptr. Returns null if the field has no default value.

Parameters

Source Code

Source code
pub inline fn defaultValue(comptime sf: StructField) ?sf.type {
    const dp: *const sf.type = @ptrCast(@alignCast(sf.default_value_ptr orelse return null));
    return dp.*;
}
