Struct ConvertColors 

pub struct ConvertColors {
    pub method: Option<Method>,
}

Converts color references to their shortest equivalent.

Colors are minified using lightningcss’ minification.

Differences to SVGO

There’s fewer options for colour conversion in exchange for more effective conversions.

Correctness

By default this job should never visually change the document.

If the Method::CurrentColor is used all colours will inherit their text colour, which may be different to the original.

Errors

If lightningcss fails to parse or serialize CSS values.

Fields

method: Option<Method>

Specifies how colours should be converted.

impl<'input, 'arena> Visitor<'input, 'arena> for ConvertColors

type Error = JobsError<'input>

The type of errors which may be produced by the visitor

fn prepare( &self, _document: &Element<'input, 'arena>, _context: &mut Context<'input, 'arena, '_>, ) -> Result<PrepareOutcome, Self::Error>

After analysing the document, determines whether any extra features such as style parsing or ignoring the tree is needed

fn element( &self, element: &Element<'input, 'arena>, _context: &mut Context<'input, 'arena, '_>, ) -> Result<(), Self::Error>

Visits a element

fn document( &self, document: &Element<'input, 'arena>, context: &Context<'input, 'arena, '_>, ) -> Result<(), Self::Error>

Visits the document

fn exit_document( &self, document: &Element<'input, 'arena>, context: &Context<'input, 'arena, '_>, ) -> Result<(), Self::Error>

Exits the document

fn exit_element( &self, element: &Element<'input, 'arena>, context: &mut Context<'input, 'arena, '_>, ) -> Result<(), Self::Error>

Exits a element

fn doctype( &self, doctype: &'arena Node<'input, 'arena>, ) -> Result<(), Self::Error>

Visits the doctype

fn style(&self, style: &'arena Node<'input, 'arena>) -> Result<(), Self::Error>

Visits the text of a style element

fn text_or_cdata( &self, node: &'arena Node<'input, 'arena>, ) -> Result<(), Self::Error>

Visits a text or cdata node

fn comment( &self, comment: &'arena Node<'input, 'arena>, ) -> Result<(), Self::Error>

Visits a comment

fn processing_instruction( &self, processing_instruction: &'arena Node<'input, 'arena>, context: &Context<'input, 'arena, '_>, ) -> Result<(), Self::Error>

Visits a processing instruction

fn start( &self, root: &'arena Node<'input, 'arena>, allocator: Allocator<'input, 'arena>, ) -> Result<PrepareOutcome, Self::Error>

Creates context for root and visits it

fn start_with_path( &self, root: &'arena Node<'input, 'arena>, allocator: Allocator<'input, 'arena>, path: Option<PathBuf>, ) -> Result<PrepareOutcome, Self::Error>

Starts visiting the document, adding the path to the visitor’s context

fn start_with_info( &self, root: &Element<'input, 'arena>, info: &Info<'input, 'arena>, flags: Option<ContextFlags>, ) -> Result<PrepareOutcome, Self::Error>

Creates context for root using the provided information and visits it

fn start_with_context( &self, root: &Element<'input, 'arena>, context: &mut Context<'input, 'arena, '_>, ) -> Result<PrepareOutcome, Self::Error>

Starts visiting the document, using an already existing visitor’s context

fn visit( &self, element: &Element<'input, 'arena>, context: &mut Context<'input, 'arena, '_>, ) -> Result<(), Self::Error>

Visits an element and it’s children

fn visit_children( &self, parent: &Element<'input, 'arena>, context: &mut Context<'input, 'arena, '_>, ) -> Result<(), Self::Error>

Visits the children of an element
