Struct style::context::StackLimitChecker

pub struct StackLimitChecker {
    lower_limit: usize,
}

Expand description

A helper type for stack limit checking. This assumes that stacks grow down, which is true for all non-ancient CPU architectures.

Fields§

§lower_limit: usize

Implementations§

source §

impl StackLimitChecker

source

pub fn new(stack_size_limit: usize) -> Self

Create a new limit checker, for this thread, allowing further use of up to |stack_size| bytes beyond (below) the current stack pointer.

source

pub fn limit_exceeded(&self) -> bool

Checks whether the previously stored stack limit has now been exceeded.

source

fn get_sp() -> usize
