Trait burn::serde::ser::Error

source ·
pub trait Error: Sized + Error {
    // Required method
    fn custom<T>(msg: T) -> Self
       where T: Display;
}
Expand description

Trait used by Serialize implementations to generically construct errors belonging to the Serializer against which they are currently running.

§Example implementation

The example data format presented on the website shows an error type appropriate for a basic JSON data format.

Required Methods§

source

fn custom<T>(msg: T) -> Self
where T: Display,

Used when a Serialize implementation encounters any error while serializing a type.

The message should not be capitalized and should not end with a period.

For example, a filesystem Path may refuse to serialize itself if it contains invalid UTF-8 data.

use serde::ser::{self, Serialize, Serializer};

impl Serialize for Path {
    fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>
    where
        S: Serializer,
    {
        match self.to_str() {
            Some(s) => serializer.serialize_str(s),
            None => Err(ser::Error::custom("path contains invalid UTF-8 characters")),
        }
    }
}

Object Safety§

This trait is not object safe.
