Struct GrowableBuffer 

pub struct GrowableBuffer { /* private fields */ }

Implementations

impl GrowableBuffer

pub fn new( device: &Device, physical_device: PhysicalDevice, instance: &Instance, usage: BufferUsageFlags, initial_capacity: usize, ) -> Result<Self>

pub fn buffer(&self) -> Buffer

pub fn capacity(&self) -> usize

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn upload(&mut self, bytes: &[u8]) -> Result<bool>

Replaces the buffer’s contents with bytes, growing the underlying GPU buffer first if it isn’t large enough. Returns true if the underlying vk::Buffer handle changed (a reallocation happened) - callers that keep a descriptor pointing at this buffer must rewrite that descriptor when this returns true.
