# [−][src]Trait serde::de::DeserializeOwned

    pub trait DeserializeOwned: for<'de> Deserialize<'de> { }

A data structure that can be deserialized without borrowing any data from the deserializer.

This is primarily useful for trait bounds on functions. For example a `from_str` function may be able to deserialize a data structure that borrows from the input string, but a `from_reader` function may only deserialize owned data.

    # use serde::de::{Deserialize, DeserializeOwned};
    # use std::io::{Read, Result};
    #
    # trait Ignore {
    fn from_str<'a, T>(s: &'a str) -> Result<T>
    where
        T: Deserialize<'a>;

    fn from_reader<R, T>(rdr: R) -> Result<T>
    where
        R: Read,
        T: DeserializeOwned;
    # }

# Lifetime

The relationship between `Deserialize` and `DeserializeOwned` in trait bounds is explained in more detail on the page Understanding deserializer lifetimes.

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
