class BufferData

Defined at line 246 of file ../../src/connectivity/lib/network-device/cpp/network_device_client.h

A collection of `BufferRegion`s and metadata associated with a `Buffer`.

Public Methods

bool is_loaded ()

Returns true if this `BufferData` contains at least 1 `BufferRegion`.

Defined at line 249 of file ../../src/connectivity/lib/network-device/cpp/network_device_client.h

uint32_t parts ()

The number of `BufferRegion`s in this `BufferData`.

Defined at line 251 of file ../../src/connectivity/lib/network-device/cpp/network_device_client.h

BufferData & operator= (BufferData && )

Move assignment deleted to abide by `Buffer` destruction semantics.

See `Buffer` for more details.

Defined at line 286 of file ../../src/connectivity/lib/network-device/cpp/network_device_client.h

BufferRegion & part (size_t idx)

Retrieves a `BufferRegion` part from this `BufferData`.

Crashes if `idx >= parts()`.

const BufferRegion & part (size_t idx)

Defined at line 977 of file ../../src/connectivity/lib/network-device/cpp/network_device_client.cc

uint32_t len ()

The total length, in bytes, of the buffer.

Defined at line 1026 of file ../../src/connectivity/lib/network-device/cpp/network_device_client.cc

size_t Write (const void * src, size_t len)

Writes up to `len` bytes from `src` into the buffer, returning the number of bytes written.

Defined at line 1030 of file ../../src/connectivity/lib/network-device/cpp/network_device_client.cc

size_t Read (void * dst, size_t len)

Reads up to `len` bytes from the buffer into `dst`, returning the number of bytes read.

Defined at line 1083 of file ../../src/connectivity/lib/network-device/cpp/network_device_client.cc

size_t Write (const BufferData & data)

Writes the contents of `data` into this buffer, returning the number of bytes written.

Defined at line 1043 of file ../../src/connectivity/lib/network-device/cpp/network_device_client.cc

zx_status_t PadTo (size_t size)

Zero pads buffer to total size `size`.

Returns `ZX_ERR_BUFFER_TOO_SMALL` if buffer doesn't have enough available space to be padded

to size. No-op and returns `ZX_OK` if `len()` is at least `size`.

Defined at line 1072 of file ../../src/connectivity/lib/network-device/cpp/network_device_client.cc
