If buffer is too small to contain all of the info, this function returns Error.BufferTooSmall. You should call getInfoSize first to determine how big the buffer should be to safely call this function.

Parameters

info:std.meta.Tag(Info)
buffer:[]align(@alignOf(@FieldType(Info, @tagName(info)))) u8
