Function abi_stable::std_types::cow::deserialize_borrowed_str

pub fn deserialize_borrowed_str<'de, 'a, D>(
    deserializer: D
) -> Result<RCow<'a, str>, D::Error> where
    D: Deserializer<'de>,
    'de: 'a, 

Deserializes an RCow<'a,str> that borrows the string from the deserializer whenever possible.

Example

Defining a type containing an RCow<'a,str> which borrows from the deserializer.

use abi_stable::std_types::cow::{
    deserialize_borrowed_str,
    RCow,
};

use serde::{Deserialize,Serialize};


#[derive(Debug,Deserialize,Serialize,PartialEq)]
pub struct TheSlice<'a>{
    #[serde(borrow,deserialize_with="deserialize_borrowed_str")]
    slice:RCow<'a,str>,
}


let the_slice=TheSlice{ slice:RCow::from("That's a lot of fish.") };

let string=serde_json::to_string(&the_slice).unwrap();

let deserialized_slice=serde_json::from_str::<TheSlice<'_>>(&string).unwrap();

assert_eq!(the_slice,deserialized_slice);

assert!( deserialized_slice.slice.is_borrowed() );
