Struct peter_engine::graphics::ResizingBuffer

pub struct ResizingBuffer<T> {
    pub label: String,
    pub usage: BufferUsages,
    pub buffer_and_len: Option<(Buffer, usize)>,
    pub contents: Vec<T>,
}

Fields

label: String

usage: BufferUsages

buffer_and_len: Option<(Buffer, usize)>

The size of the buffer in bytes is std::mem::size_of::<T>() * len.

contents: Vec<T>
