Struct StackTrace

pub struct StackTrace {
    pub stack_trace_key: Option<u64>,
    pub program_addresses: Option<Vec<u64>>,
    /* private fields */
}

A stack trace.

In order to avoid exceeding the channel’s maximum message size, stack traces can be split in multiple chunks. Receivers should be prepared to handle multiple StackTrace elements with the same key and reassemble them by concatenating their program addresses.

Fields

stack_trace_key: Option<u64>

A number that uniquely identifies this stack trace within the parent snapshot.

program_addresses: Option<Vec<u64>>

The program counters corresponding to stack each frame.

Entries are listed in reverse call order: the first entry refers to the leaf frame, and the last entry refers to the frame at the root of the call stack.

Trait Implementations

impl Clone for StackTrace

fn clone(&self) -> StackTrace

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StackTrace

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<StackTrace, D> for StackTrace

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

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

impl Default for StackTrace

fn default() -> StackTrace

Returns the “default value” for a type.

impl<D: ResourceDialect> Encode<StackTrace, D> for &StackTrace

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

fn eq(&self, other: &StackTrace) -> 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 TypeMarker for StackTrace

type Owned = StackTrace

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 StackTrace

type Borrowed<'a> = &'a StackTrace

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(value: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

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