pub struct ProcessingStack<I> { /* private fields */ }

Context processing stack.

Contains the list of the loaded contexts to detect loops.

Implementations

impl<I> ProcessingStack<I>

pub fn new() -> Self

Creates a new empty processing stack.

pub fn is_empty(&self) -> bool

Checks if the stack is empty.

pub fn cycle(&self, url: &I) -> bool

where I: PartialEq,

Checks if the given URL is already in the stack.

This is used for loop detection.

pub fn push(&mut self, url: I) -> bool

where I: PartialEq,

Push a new URL to the stack, unless it is already in the stack.

Returns true if the URL was successfully added or false if a loop has been detected.
