Struct anyvec::AnyVec
[−]
[src]
pub struct AnyVec { /* fields omitted */ }A growable list type with dynamic typing.
It can store anything that implements the Any trait.
Methods
impl AnyVec[src]
fn new() -> Self
Constructs a new, empty AnyVec.
fn with_capacity(capacity: usize, avg_type_size: usize) -> Self
Constructs a new, empty AnyVec with specified capacity.
Since we do not type sizes ahead, an average type size avg_type_size must be specified.
fn capacity(&self, type_size: usize) -> usize
Returns the number of elements the vector can hold without reallocating.
fn reserve(&mut self, additional: usize, avg_type_size: usize)
Reserves capacity for at least additional more elements.
Since we do not type sizes ahead, an average type size avg_type_size must be specified.
Panics
Panics if the new capacity overflows usize.
fn reserve_exact(&mut self, additional: usize, avg_type_size: usize)
Reserves capacity for exactly additional more elements.
Since we do not type sizes ahead, an average type size avg_type_size must be specified.
Panics
Panics if the new capacity overflows usize.
fn shrink_to_fit(&mut self)
Shrinks the capacity of the vector as much as possible.
fn truncate(&mut self, len: usize)
Shortens the vector to be len elements long.
fn insert<T: Any>(&mut self, index: usize, element: T)
Inserts an element at position index in the vector.
Shifts elements after position index to the right.
Panics
Panics if index is greater than the vector's length.
fn remove_and_return<T: Any>(&mut self, index: usize) -> Result<T, String>
Removes and returns the element at position index.
Shifts elements after position index to the left.
Panics
Panics if index is out of bounds.
fn remove(&mut self, index: usize)
Removes and returns the element at position index.
Shifts elements after position index to the left.
Panics
Panics if index is out of bounds.
fn is<T: Any>(&self, index: usize) -> Option<bool>
Returns if element at position index is of type T,
or None if the index is out of bounds.
fn get<T: Any>(&self, index: usize) -> Result<Option<&T>, String>
Returns element at position index or None if the index is out of bounds.
fn get_mut<T: Any>(&self, index: usize) -> Result<Option<&mut T>, String>
Returns mutable reference to element at position index,
or None if the index is out of bounds.
fn push<T: Any>(&mut self, value: T)
Appends an element to the back of a collection.
Panics
Panics if the number of elements in the vector overflows a usize.
fn pop<T: Any>(&mut self) -> Result<Option<T>, String>
Returns the last element of the vector, or None if it is empty.
fn append(&mut self, other: &mut AnyVec)
Moves all the elements of other into Self, leaving other empty.
Panics
Panics if the number of elements in the vector overflows a usize.
fn clear(&mut self)
Clears the vector.
fn len(&self) -> usize
Returns the number of elements in the vector.
fn is_empty(&self) -> bool
Returns if the vector is empty.
