[−][src]Function serde_hashkey::to_key_with_ordered_float
pub fn to_key_with_ordered_float<T>(
value: &T
) -> Result<Key<OrderedFloatPolicy>, Error> where
T: Serialize,
Serialize the given value to a Key using OrderedFloatPolicy.
This policy is derived from the OrderedFloat
type in the
ordered-float
crate.
Examples
