Struct CustomSerDes 

pub struct CustomSerDes<T, S, D>
where
    T: Send + Sync,
    S: Fn(&T, &SerDesContext) -> Result<String, SerDesError> + Send + Sync,
    D: Fn(&str, &SerDesContext) -> Result<T, SerDesError> + Send + Sync,
{ /* private fields */ }

A custom serializer/deserializer that delegates to user-provided closures.

This struct allows users to provide custom serialization behavior without implementing the sealed SerDes trait directly.

Type Parameters

• T - The type to serialize/deserialize
• S - The serialization closure type
• D - The deserialization closure type

Example

use durable_execution_sdk::serdes::{custom_serdes, SerDes, SerDesContext, SerDesError};

// Create a custom serializer for strings that adds a prefix
let serdes = custom_serdes::<String, _, _>(
    |value, _ctx| Ok(format!("PREFIX:{}", value)),
    |data, _ctx| {
        data.strip_prefix("PREFIX:")
            .map(|s| s.to_string())
            .ok_or_else(|| SerDesError::deserialization("Missing PREFIX"))
    },
);

Trait Implementations

impl<T, S, D> Debug for CustomSerDes<T, S, D>

where T: Send + Sync, S: Fn(&T, &SerDesContext) -> Result<String, SerDesError> + Send + Sync, D: Fn(&str, &SerDesContext) -> Result<T, SerDesError> + Send + Sync,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T, S, D> SerDes<T> for CustomSerDes<T, S, D>

where T: Send + Sync, S: Fn(&T, &SerDesContext) -> Result<String, SerDesError> + Send + Sync, D: Fn(&str, &SerDesContext) -> Result<T, SerDesError> + Send + Sync,

fn serialize( &self, value: &T, context: &SerDesContext, ) -> Result<String, SerDesError>

Serializes a value to a string representation.

fn deserialize( &self, data: &str, context: &SerDesContext, ) -> Result<T, SerDesError>

Deserializes a string representation back to a value.
