Struct ProcessingStack 

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() -> ProcessingStack<I>

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.

where I: Clone,

fn clone(&self) -> ProcessingStack<I>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<I> Default for ProcessingStack<I>

fn default() -> ProcessingStack<I>
