Enum Op 

pub enum Op {
    Fill(Fill),
    Stroke(Stroke),
    Image(ImageOp),
    Mask(MaskOp),
}

One step of a drawing.

Variants

Fill(Fill)

A path’s inside painted (non-zero winding).

Stroke(Stroke)

A path’s outline painted, round-joined and capped.

Image(ImageOp)

An image in a box.

Mask(MaskOp)

A one-color picture, a bit a pixel, in a box (a pixel font’s glyph).

Trait Implementations

impl Clone for Op

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Op

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

Formats the value using the given formatter.

impl PartialEq for Op

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Schema for Op

fn shape() -> Shape

What the format looks like.

fn read(v: &ValueRef<'_>, cx: &mut Reader<'_>) -> Option<Self>

Reads v. Problems go to cx at its current path; None when the value couldn’t be read (the problem is in cx).

fn write(&self) -> Value

The value, as the format writes it.

fn absent() -> Option<Self>

The value of a field that isn’t there — None: the field is required.

fn skip(&self) -> bool

Whether a struct leaves this field out when writing it.

fn encode(&self, w: &mut Writer)

Writes itself in the binary form, straight — Schema::write’s value encoded, unless the type knows better (derived ones do).

fn decode(d: &mut Decoder<'_>) -> Option<Self>

Reads itself from the binary form, straight; None when it isn’t what Schema::encode writes — then read_bytes reads the slow way, which says what’s wrong. Through a value unless the type knows better (derived ones do).

fn pack(&self, p: &mut Packer)

Packs itself into a frame (crate::frame): its binary form as bytes, unless the type packs itself (derived ones and plain types do).

fn unpack(u: &mut Unpacker<'_>) -> Option<Self>

Reads itself out of a frame; None if the bytes aren’t what Schema::pack writes.

fn pack_list(items: &[Self], p: &mut Packer)

A list of these packed: a count, then each one (floats raw).

fn unpack_list(u: &mut Unpacker<'_>) -> Option<Vec<Self>>

A list of these out of a frame.

fn encode_list(items: &[Self], w: &mut Writer)

A list of these written straight (numbers pack theirs).

fn decode_list(d: &mut Decoder<'_>) -> Option<Vec<Self>>

A list of these read straight.
