Struct ArrayBuilder 

pub struct ArrayBuilder<T> { /* private fields */ }

A simple growable buffer.

Upstream hands out ArraySlices aliasing the builder’s array; here the builder owns a Vec<T> and ranges are borrowed as plain slices.

Implementations

impl<T> ArrayBuilder<T>

pub const fn new() -> Self

pub fn length(&self) -> usize

The number of items.

pub fn capacity(&self) -> usize

The allocated capacity.

pub fn add_item(&mut self, value: T)

Appends one item.

pub fn clear(&mut self)

Removes every item, keeping the storage.

pub fn reset(&mut self)

Drops the storage (C# arrayBuilder = default).

pub fn as_span(&self) -> &[T]

The items.

pub fn as_span_mut(&mut self) -> &mut [T]

The items, mutably.

pub fn as_slice(&self, start: usize, length: usize) -> &[T]

length items starting at start.

pub fn as_slice_to(&self, length: usize) -> &[T]

The first length items (the original’s AsSlice(length); its AsSlice() is as_span).

pub fn as_slice_mut(&mut self, start: usize, length: usize) -> &mut [T]

length items starting at start, mutably.

impl<T: Clone + Default> ArrayBuilder<T>

pub fn set_length(&mut self, value: usize)

Sets the number of items; new items are default values.

pub fn add(&mut self, length: usize) -> &mut [T]

Appends length default items and returns them.

pub fn add_slice(&mut self, value: &[T]) -> &mut [T]

Appends a copy of value and returns the appended range.

Trait Implementations

impl<T: Debug> Debug for ArrayBuilder<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Default> Default for ArrayBuilder<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T> Index<usize> for ArrayBuilder<T>

type Output = T

The returned type after indexing.

fn index(&self, index: usize) -> &T

Performs the indexing (container[index]) operation.

impl<T> IndexMut<usize> for ArrayBuilder<T>

fn index_mut(&mut self, index: usize) -> &mut T

Performs the mutable indexing (container[index]) operation.
