A Buffer is an object containing a pointer to a piece of contiguous memory with a particular size.
buffer(x)
R object. Only raw, numeric and integer vectors are currently supported
an instance of Buffer
that borrows memory from x
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
#> [1] TRUE
my_buffer$ZeroPadding()
my_buffer$size
#> [1] 32
my_buffer$capacity
#> [1] 32
