Struct CommonPacketCaptureParams 

pub struct CommonPacketCaptureParams {
    pub interfaces: Option<InterfaceSpecifier>,
    pub bpf_program: Option<VerifiedProgram>,
    pub snap_len: Option<u32>,
    /* private fields */
}

Parameters common to all packet capturing modes.

Fields

interfaces: Option<InterfaceSpecifier>

Which interface(s) to capture on.

Required.

bpf_program: Option<VerifiedProgram>

eBPF program for deciding which packets are included in the capture. The program must not make use of any eBPF-only features not present in cBPF. The program must be of type BPF_PROG_TYPE_SOCKET_FILTER and have been verified as such.

Optional.

snap_len: Option<u32>

Number of bytes from the start of each packet to save in the capture. Truncation only happens at the end of the packet, no headers are skipped.

Optional, DEFAULT_SNAP_LEN is used if absent or 0 is passed.

Trait Implementations

impl Debug for CommonPacketCaptureParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Decode<CommonPacketCaptureParams, DefaultFuchsiaResourceDialect> for CommonPacketCaptureParams

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, DefaultFuchsiaResourceDialect>, offset: usize, depth: Depth, ) -> Result<()>

Decodes an object of type T from the decoder’s buffers into self.

impl Default for CommonPacketCaptureParams

fn default() -> CommonPacketCaptureParams

Returns the “default value” for a type.

impl Encode<CommonPacketCaptureParams, DefaultFuchsiaResourceDialect> for &mut CommonPacketCaptureParams

unsafe fn encode( self, encoder: &mut Encoder<'_, DefaultFuchsiaResourceDialect>, offset: usize, depth: Depth, ) -> Result<()>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for CommonPacketCaptureParams

fn eq(&self, other: &CommonPacketCaptureParams) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ResourceTypeMarker for CommonPacketCaptureParams

type Borrowed<'a> = &'a mut CommonPacketCaptureParams

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &mut Self::Owned. There are three cases:

fn take_or_borrow<'a>( value: &'a mut <Self as TypeMarker>::Owned, ) -> Self::Borrowed<'a>

Cheaply converts from &mut Self::Owned to Self::Borrowed. For HandleBased types this is “take” (it returns an owned handle and replaces value with Handle::invalid), and for all other types it is “borrow” (just converts from one reference to another).

impl TypeMarker for CommonPacketCaptureParams

type Owned = CommonPacketCaptureParams

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.
