Code
Hey,I encountered a panic in the compiler version 1.76.0.
Using nightly 1.78.0 helps as it points the error in my code and do not crash the reason is that my first argument:
fn serialize_price_matrix<T, S>(_: &Vec<Vec>, serializer: S should be
fn serialize_price_matrix<T, S>(_: &T, serializer: S
12 | #[serde(serialize_with = "serialize_price_matrix")]
| ^^^^^^^^^^^^^^^^^^^^^^^^ cannot infer type of the type parameter `T` declared on the function `serialize_price_matrix`
use serde::{Serialize, Serializer};
fn serialize_price_matrix<T, S>(_: &Vec<Vec<f64>>, serializer: S) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>
where
S: Serializer,
{
serializer.serialize_f64(0.0)
}
#[derive(Serialize)]
pub(crate) struct Matrix {
#[serde(serialize_with = "serialize_price_matrix")]
matrix: Vec<Vec<f64>>,
}
fn main() {
}Meta
