Struct ClassStack 

struct ClassStack {
    open_classes: Vec<ClassInfo>,
}

This represents the stack of HTML elements. For example a macro expansion will contain other elements which might themselves contain other elements (like macros).

This allows to easily handle HTML tags instead of having a more complicated state machine to keep track of which tags are open.

Fields

open_classes: Vec<ClassInfo>

Implementations

impl ClassStack

fn new() -> Self

fn enter_elem<W: Write>( &mut self, out: &mut W, href_context: &Option<HrefContext<'_, '_>>, new_class: Class, closing_tag: Option<&'static str>, )

fn exit_elem(&mut self)

This sets the pending_exit field to true. Meaning that if we try to push another stack which is not compatible with this one, it will exit the current one before adding the new one.

fn last_class(&self) -> Option<Class>

fn last_class_is_open(&self) -> bool

fn close_last_if_needed<W: Write>(&mut self, out: &mut W)

fn push<W: Write>( &mut self, out: &mut W, href_context: &Option<HrefContext<'_, '_>>, class: Option<Class>, text: Cow<'_, str>, needs_escape: bool, )

fn empty_stack<W: Write>(&mut self, out: &mut W) -> Vec<Class>

This method closes all open tags and returns the list of Class which were not already closed (ie pending_exit set to true).

It is used when starting a macro expansion: we need to close all HTML tags and then to reopen them inside the newly created expansion HTML tag. Same goes when we close the expansion.

Trait Implementations

impl Debug for ClassStack

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
