Struct BlocksBuilder

pub struct BlocksBuilder<T>(pub Vec<T>);

A convenient wrapper around a vector of blocks. This is used instead of id_arena, since the latter is harder to clone and modify.

Tuple Fields

0: Vec<T>

Implementations

impl<T: Default> BlocksBuilder<T>

pub fn new() -> Self

pub fn alloc(&mut self, block: T) -> BlockId

pub fn alloc_empty(&mut self) -> BlockId

Allocate a new block ID. The block itself should be populated later.

pub fn set_block(&mut self, id: BlockId, block: T)

Sets an already-allocated block.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn build(self) -> Option<Blocks<T>>

Trait Implementations

impl<T: Clone> Clone for BlocksBuilder<T>

fn clone(&self) -> BlocksBuilder<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for BlocksBuilder<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for BlocksBuilder<T>

fn default() -> BlocksBuilder<T>

Returns the “default value” for a type.

impl<T: PartialEq> PartialEq for BlocksBuilder<T>

fn eq(&self, other: &BlocksBuilder<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
