Function serde_any::ser::to_string_pretty

pub fn to_string_pretty<T>(value: &T, format: Format) -> Result<String, Error> where
    T: Serialize, 

Serialize to a pretty-printed String

Not all serialization formats support pretty printing. In such cases, the output from this function will be identical to the output of to_string.

Errors

If serialization fails, the format-specific Error variant is returned, with the underlying error as its cause.

Example

#[macro_use]
extern crate serde;
extern crate serde_any;
extern crate failure;

use serde_any::Format;
use failure::Error;

#[derive(Serialize, Debug)]
struct Person {
    name: String,
    knowledge: u32,
}

fn main() -> Result<(), Error> {
    let bran = Person {
        name: "Brandon Stark".to_string(),
        knowledge: 100,
    };
    let data = serde_any::to_string_pretty(&bran, Format::Toml)?;
    println!("{}", data);
    assert_eq!(&data[..], "name = \'Brandon Stark\'\nknowledge = 100\n");
    Ok(())
}
