Struct CallInfoCursor 

pub struct CallInfoCursor(/* private fields */);

Nullable traversal position in a thread’s call-info array.

Unsafe navigation requires both cursors to belong to the same live array; reallocation or thread destruction invalidates every cursor.

Implementations

impl CallInfoCursor

pub const fn as_ptr(&self) -> *mut RawCallInfo

Returns the current traversal address, which may be null.

CallInfo array growth invalidates cursors into the old allocation.

pub const fn from_ptr(raw: *mut RawCallInfo) -> Self

pub const fn is_null(&self) -> bool

pub unsafe fn call_info_unchecked(&self) -> CallInfo

pub fn call_info(&self) -> Option<CallInfo>

pub unsafe fn add(self, count: usize) -> Self

pub unsafe fn sub(self, count: usize) -> Self

pub unsafe fn offset(self, count: isize) -> Self

pub unsafe fn offset_from(self, other: Self) -> isize

Trait Implementations

impl AsRef<CallInfoCursor> for CallInfoCursor

impl Copy for CallInfoCursor

impl Eq for CallInfoCursor

impl Ord for CallInfoCursor

fn cmp(&self, other: &CallInfoCursor) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

impl PartialEq for CallInfoCursor

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for CallInfoCursor

fn partial_cmp(&self, other: &CallInfoCursor) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
