pub fn de_opt_i64<'de, D: Deserializer<'de>>(
d: D,
) -> Result<Option<i64>, D::Error>Expand description
An optional number that may arrive as 412, “412”, “#412”, null, or “none”.
Anything unparseable yields None rather than failing. A duplicate pointer is decoration on a verdict that stands without it, and taking a whole batch down over one stray string costs a second full repo pass to learn nothing.
