impl<T> Serialize for Vec<T>
where
T: Serialize,
{
fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>
where
S: Serializer,
{
let mut seq = serializer.serialize_seq(Some(self.len()))?;
for element in self {
seq.serialize_element(element)?;
}
seq.end()
}
}
Example implementation
The example data format presented on the website demonstrates an
implementation of SerializeSeq
for a basic JSON data format.
Associated Types
type Ok
Must match the Ok
type of our Serializer
.
type Error: Error
Must match the Error
type of our Serializer
.
Required methods
fn serialize_element<T: ?Sized>(&mut self, value: &T) -> Result<(), Self::Error> where
T: Serialize,
T: Serialize,
Serialize a sequence element.
fn end(self) -> Result<Self::Ok, Self::Error>
Finish serializing a sequence.
