Trait serde::ser::Error
[−]
[src]
pub trait Error: Sized + Error { fn custom<T>(msg: T) -> Self
where
T: Display; }
Trait used by Serialize
implementations to generically construct
errors belonging to the Serializer
against which they are
currently running.
Required Methods
fn custom<T>(msg: T) -> Self where
T: Display,
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")), } } }
