Function declarationInfo [src]

Prototype

pub fn declarationInfo(comptime T: type, comptime decl_name: []const u8) Type.Declaration

Parameters

T: typedecl_name: []const u8

Example

 test declarationInfo {
    const E1 = enum {
        A,

        pub fn a() void {}
    };
    const S1 = struct {
        pub fn a() void {}
    };
    const U1 = union {
        b: u8,

        pub fn a() void {}
    };

    const infos = comptime [_]Type.Declaration{
        declarationInfo(E1, "a"),
        declarationInfo(S1, "a"),
        declarationInfo(U1, "a"),
    };

    inline for (infos) |info| {
        try testing.expect(comptime mem.eql(u8, info.name, "a"));
    }
}
