Struct ArenaVec 

pub struct ArenaVec<'a> { /* private fields */ }

A vector-like structure backed by arena memory.

This provides push/extend operations while using arena memory. When dropped, the arena space is not reclaimed (arena is bump-only).

Implementations

impl<'a> ArenaVec<'a>

pub fn push(&mut self, value: u8) -> bool

Push a byte to the vector.

Returns false if the vector is at capacity and cannot grow.

pub fn extend_from_slice(&mut self, data: &[u8]) -> bool

Extend the vector with bytes from a slice.

Returns false if there’s not enough space.

pub fn len(&self) -> usize

Get the length of the vector.

pub fn is_empty(&self) -> bool

Check if the vector is empty.

pub fn as_slice(&self) -> &[u8]

Get a slice of the vector contents.

pub fn to_vec(&self) -> Vec<u8>

Convert to a regular Vec (copies the data).
