Expand description

Returned from Serializer::serialize_seq.

Example use

ⓘ
use serde::ser::{Serialize, Serializer, SerializeSeq};

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

Must match the Ok type of our Serializer.

Must match the Error type of our Serializer.

Required methods
