Struct LinearPrefix 

pub struct LinearPrefix<S, W> { /* private fields */ }

Mutable view of a linear top prefix over an unchanged hidden floor.

The hidden floor may still be branched. Use Self::floor_is_empty to test whether the prefix represents one complete concrete stack.

Implementations

impl<S, W> LinearPrefix<S, W>

where S: Clone + Eq + Hash, W: Weight,

pub fn len(&self) -> usize

Return the number of values in the accessible linear prefix.

pub fn is_empty(&self) -> bool

Return whether the accessible prefix is empty.

pub fn get(&self, depth_from_top: usize) -> Option<&S>

Return a visible value by depth from the top.

pub fn floor_is_empty(&self) -> bool

Return whether the hidden floor is exactly the empty stack.

pub fn push(&mut self, value: S)

Push one value onto the prefix.

pub fn popn(&mut self, count: usize) -> usize

Pop values from the prefix and return the number that reached its floor.

pub fn into_gss(self) -> WeightedGss<S, W>

Convert the view back into a weighted GSS.

Trait Implementations

impl<S: Clone, W: Clone> Clone for LinearPrefix<S, W>

fn clone(&self) -> LinearPrefix<S, W>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
