Trait DeduplicateSharedSize

pub trait DeduplicateSharedSize<Size: Size>: Sized {
    type Report;
    type Error;

    // Required method
    fn deduplicate(
        self,
        data_tree: &mut DataTree<OsStringDisplay, Size>,
    ) -> Result<Self::Report, Self::Error>;
}

Ability to correct the sizes in a DataTree by reducing the size of recorded shared links.

The input tree is assumed to be not yet deduplicated.

Required Associated Types

type Report

Report returned when DeduplicateSharedSize::deduplicate succeeds.

type Error

Error returned when DeduplicateSharedSize::deduplicate fails.

Required Methods

fn deduplicate( self, data_tree: &mut DataTree<OsStringDisplay, Size>, ) -> Result<Self::Report, Self::Error>

Correct the sizes in a DataTree by reducing the size of recorded shared links.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
