pub trait IntoDeserializer<'de, E: Error = Error> {
    type Deserializer: Deserializer<'de, Error = E>;

    // Required method
    fn into_deserializer(self) -> Self::Deserializer;
}
Expand description

Converts an existing value into a Deserializer from which other values can be deserialized.

Lifetime

The 'de lifetime of this trait is the lifetime of data that may be borrowed from the resulting Deserializer. See the page Understanding deserializer lifetimes for a more detailed explanation of these lifetimes.

Example

use std::str::FromStr;
use serde::Deserialize;
use serde::de::{value, IntoDeserializer};

#[derive(Deserialize)]
enum Setting {
    On,
    Off,
}

impl FromStr for Setting {
    type Err = value::Error;

    fn from_str(s: &str) -> Result<Self, Self::Err> {
        Self::deserialize(s.into_deserializer())
    }
}

Required Associated Types§
