Struct fidl_fuchsia_memory_heapdump_client::BlockContents

pub struct BlockContents {
    pub address: Option<u64>,
    pub contents: Option<Vec<u8>>,
    /* private fields */
}

The contents of an allocated memory block.

In order to avoid exceeding the channel’s maximum message size, bigger blocks can be split in chunks. Receivers should be prepared to handle multiple BlockContents with the same address and reassemble them by concatenating their payloads. Each block’s reassembled size always matches the size field of the corresponding Allocation.

Fields

address: Option<u64>

The address of the corresponding memory block.

contents: Option<Vec<u8>>

The payload.

Trait Implementations

impl Clone for BlockContents

fn clone(&self) -> BlockContents

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BlockContents

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

Formats the value using the given formatter.

impl Decode<BlockContents> for BlockContents

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<'_>, offset: usize, depth: Depth ) -> Result<()>

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

impl Default for BlockContents

fn default() -> BlockContents

Returns the “default value” for a type.

impl Encode<BlockContents> for &BlockContents

unsafe fn encode( self, encoder: &mut Encoder<'_>, 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 BlockContents

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TypeMarker for BlockContents

type Owned = BlockContents

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.

impl ValueTypeMarker for BlockContents

type Borrowed<'a> = &'a BlockContents

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

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

Cheaply converts from &Self::Owned to Self::Borrowed.
