This crash also occurs with this simplified code: use serde::{Serialize, Serializer};
struct Type;
impl Serialize for Type {
fn serialize<S>(&self, _: S) -> Result<S::Ok, S::Error>
where
S: Serializer
{
#[derive(Serialize)]
struct S;
}
}It happens with use serde::{Deserialize, Deserializer};
struct Type;
impl<'de> Deserialize<'de> for Type {
fn deserialize<D>(_: D) -> Result<Self, D::Error>
where
D: Deserializer<'de>
{
#[derive(Serialize)]
struct S;
}
