Trait serde::ser::Error [] [src]

pub trait Error: Sized + Error {
    fn custom<T: Display>(msg: T) -> Self;

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

Required Methods

Raised when a Serialize implementation encounters a general 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.

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