Struct similar::algorithms::NoFinishHook

pub struct NoFinishHook<D: DiffHook>(/* private fields */);

Wrapper DiffHook that prevents calls to DiffHook::finish.

This hook is useful in situations where diff hooks are composed but you want to prevent that the finish hook method is called.

Implementations

impl<D: DiffHook> NoFinishHook<D>

pub fn new(d: D) -> NoFinishHook<D>

Wraps another hook.

pub fn into_inner(self) -> D

Extracts the inner hook.

Trait Implementations

impl<D: DiffHook> DiffHook for NoFinishHook<D>

type Error = <D as DiffHook>::Error

The error produced from the hook methods.

fn equal( &mut self, old_index: usize, new_index: usize, len: usize, ) -> Result<(), Self::Error>

Called when lines with indices old_index (in the old version) and new_index (in the new version) start an section equal in both versions, of length len.

fn delete( &mut self, old_index: usize, old_len: usize, new_index: usize, ) -> Result<(), Self::Error>

Called when a section of length old_len, starting at old_index, needs to be deleted from the old version.

fn insert( &mut self, old_index: usize, new_index: usize, new_len: usize, ) -> Result<(), Self::Error>

Called when a section of the new version, of length new_len and starting at new_index, needs to be inserted at position `old_index’.

fn replace( &mut self, old_index: usize, old_len: usize, new_index: usize, new_len: usize, ) -> Result<(), Self::Error>

Called when a section of the old version, starting at index old_index and of length old_len, needs to be replaced with a section of length new_len, starting at new_index, of the new version.

fn finish(&mut self) -> Result<(), Self::Error>

Always called at the end of the algorithm.
