Struct Transformer

pub struct Transformer<'a, N>where
    N: NodeInfo + 'a,
{ /* private fields */ }

Expand description

A mapping from coordinates in the source sequence to coordinates in the sequence after the delta is applied.

Implementations§

§

impl<'a, N> Transformer<'a, N>
where N: NodeInfo + 'a,

pub fn new(delta: &'a Delta<N>) -> Transformer<'a, N>

Create a new transformer from a delta.

pub fn transform(&mut self, ix: usize, after: bool) -> usize

Transform a single coordinate. The after parameter indicates whether it it should land before or after an inserted region.

pub fn interval_untouched<T>(&mut self, iv: T) -> bool
where T: IntervalBounds,

Determine whether a given interval is untouched by the transformation.

Source §

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T
where T: ?Sized,

Source §

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> DowncastSync for T
where T: Any + Send + Sync,

§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
