bool has_simple;

bool has_strides;

bool has_indirect;

Constructors

this this(): construct buffer view. Probe for capabilities this object supports.
this this(int flags): Construct buffer view. Don't probe for capabilities; assume object supports capabilities implied by flags.

Properties

buf ubyte[] buf [@property getter]: Get the raw bytes of this buffer
format string format [@property getter]: Get the struct-style format of the element type of this buffer.
itemsize itemsize [@property getter]: _
ndim int ndim [@property getter]: Get number of dimensions of this buffer.
readonly bool readonly [@property getter]: _
shape Py_ssize_t[] shape [@property getter]: _
strides Py_ssize_t[] strides [@property getter]: _
suboffsets Py_ssize_t[] suboffsets [@property getter]: _

Variables

c_contiguous bool c_contiguous;: supports PyBUF_C_CONTIGUOUS.
buffer is row-major.
fortran_contiguous bool fortran_contiguous;: supports PyBUF_F_CONTIGUOUS.
buffer is column-major
has_indirect bool has_indirect;: supports PyBUF_INDIRECT.
i.e. buffer supplies suboffsets.
has_nd bool has_nd;: supports PyBUF_ND.
i.e. buffer supplies ndim, shape.
has_simple bool has_simple;: supports PyBUF_SIMPLE.
should always be true.
has_strides bool has_strides;: supports PyBUF_STRIDES.
i.e. buffer supplies strides.
