Struct ThreadSample 

pub struct ThreadSample {
    pub os_tid: u64,
    pub stack_pointer: u64,
    pub instruction_pointer: u64,
    pub frame_pointer: u64,
    pub link_register: Option<u64>,
    pub stack_bytes: Vec<u8>,
    pub truncated: bool,
    pub kind: CaptureKind,
    pub frames: Vec<u64>,
}

One thread’s captured state.

Fields

os_tid: u64

OS thread id.

stack_pointer: u64

Stack pointer at capture time.

instruction_pointer: u64

Instruction pointer at capture time.

frame_pointer: u64

Frame pointer at capture time.

link_register: Option<u64>

Link register, on architectures that have one (aarch64).

Load-bearing there: a leaf frame’s return address lives in LR rather than on the stack, so unwinding without it loses the first frame. None on x86_64, which has no such register.

stack_bytes: Vec<u8>

Bytes copied from the stack, starting at stack_pointer.

truncated: bool

True when the stack was longer than MAX_STACK_BYTES, so the copy is a prefix. A consumer must not read a truncated capture as a complete one.

kind: CaptureKind

What stage this sample is at.

frames: Vec<u64>

Return addresses, once unwinding has run. Empty until then — check Snapshot::frames_resolved rather than inferring from emptiness, since a thread with an unwalkable stack also yields none.

Trait Implementations

impl Clone for ThreadSample

fn clone(&self) -> ThreadSample

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ThreadSample

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

Formats the value using the given formatter.
