Struct TokenHandler 

struct TokenHandler<'a, 'tcx, F: Write> {
    out: &'a mut F,
    class_stack: ClassStack,
    href_context: Option<HrefContext<'a, 'tcx>>,
    line_number_kind: LineNumberKind,
    line: u32,
    max_lines: u32,
}

This type is used as a conveniency to prevent having to pass all its fields as arguments into the various functions (which became its methods).

Fields

out: &'a mut F

class_stack: ClassStack

href_context: Option<HrefContext<'a, 'tcx>>

We need to keep the Class for each element because it could contain a Span which is used to generate links.

line_number_kind: LineNumberKind

line: u32

max_lines: u32

Implementations

impl<'a, F: Write> TokenHandler<'a, '_, F>

fn handle_backline(&mut self) -> Option<impl Display + use<F>>

fn push_token_without_backline_check( &mut self, class: Option<Class>, text: Cow<'a, str>, needs_escape: bool, )

fn push_token(&mut self, class: Option<Class>, text: Cow<'a, str>)

fn start_expansion(&mut self)

fn add_expanded_code(&mut self, expanded_code: &ExpandedCode)

fn close_expansion(&mut self)

fn close_original_tag(&mut self)

Used when we’re done with the current expansion “original code” (ie code before expansion). We close all tags inside Class::Original and only keep the ones that were not closed yet.

Trait Implementations

impl<F: Write> Debug for TokenHandler<'_, '_, F>

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

Formats the value using the given formatter.

impl<F: Write> Drop for TokenHandler<'_, '_, F>

fn drop(&mut self)

When leaving, we need to flush all pending data to not have missing content.

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.
