Struct Stack 

pub struct Stack { /* private fields */ }

A thread stack with optional guard pages.

This structure represents a single allocated stack that can be used by a thread. It handles both the memory allocation and optional guard page protection.

Implementations

impl Stack

pub fn size(&self) -> usize

Get the usable stack size in bytes.

pub fn size_class(&self) -> StackSizeClass

Get the stack size class.

pub fn stack_bottom(&self) -> *mut u8

Get a pointer to the bottom of the stack (highest address).

On most architectures, stacks grow downward, so this is where the stack pointer should be initialized.

pub fn stack_top(&self) -> *const u8

Get a pointer to the top of the stack (lowest address).

pub fn bottom(&self) -> *mut u8

Get bottom pointer (alias for stack_bottom for compatibility).

pub fn top(&self) -> *const u8

Get top pointer (alias for stack_top for compatibility).

pub fn has_guard_pages(&self) -> bool

Check if this stack has guard pages enabled.

pub fn install_canary(&self, canary: u64)

Install a stack canary value for overflow detection.

This writes a known pattern at the bottom of the usable stack that can be checked later to detect stack overflow.

Arguments

• canary - The canary value to write

pub fn check_canary(&self, expected_canary: u64) -> bool

Check if the stack canary is still intact.

Arguments

• expected_canary - The expected canary value

Returns

true if the canary is intact, false if it has been corrupted.

Trait Implementations

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

Performs copy-assignment from source.

impl Drop for Stack

fn drop(&mut self)
