A Buffer is an object containing a pointer to a piece of contiguous memory with a particular size.
R object. Only raw, numeric and integer vectors are currently supported
an instance of
Buffer that borrows memory from
buffer() lets you create an
arrow::Buffer from an R object
$is_mutable : is this buffer mutable?
$ZeroPadding() : zero bytes in padding, i.e. bytes between size and capacity
$size : size in memory, in bytes
$capacity: possible capacity, in bytes
my_buffer <- buffer(c(1, 2, 3, 4)) my_buffer$is_mutable #>  TRUE my_buffer$ZeroPadding() my_buffer$size #>  32 my_buffer$capacity #>  32
