Trait DirectFileDestination 

pub trait DirectFileDestination: Send + Sync {
    // Required methods
    fn prepare(
        &self,
        transfer_id: String,
        files: Vec<DirectFileSnapshot>,
    ) -> Result<(), DirectFileDestinationError>;
    fn write(
        &self,
        file_index: u32,
        bytes: Vec<u8>,
    ) -> Result<(), DirectFileDestinationError>;
    fn finish_file(
        &self,
        file_index: u32,
    ) -> Result<(), DirectFileDestinationError>;
    fn commit(&self) -> Result<Vec<String>, DirectFileDestinationError>;
    fn abort(&self);
}

Each selected destination belongs to one acceptance. abort must remove only newly created partial outputs; it must never delete or truncate existing files. prepare must clean its own partial preparation on error, without disturbing an already-open destination if the same object is accidentally reused.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
