Enum Generator 

pub enum Generator {
    Fill {
        paint: Paint,
    },
    Shapes {
        items: Vec<ShapeItem>,
    },
    Text {
        text: String,
        style: TextStyle,
    },
}

The picture of a generated source.

A generated picture has the canvas’s size and aspect, like a source that fills the frame at scale 1. Positions are in its normalized space, (0, 0) top-left to (1, 1) bottom-right; lengths (radii, stroke widths) are fractions of its shorter side, so the picture is the same at any render resolution. A fill or text does not change over time (a clip animates it with its transform, effects, and masks); shapes may.

Variants

Fill

Paint over the whole picture.

Fields

paint: Paint

What covers the picture.

Shapes

Shapes drawn from an ordered content tree, as an After Effects shape layer or a Lottie shape layer draws them. Unlike the other generators, its picture changes over time: every value in the tree may be keyframed, in the picture’s time.

Fields

items: Vec<ShapeItem>

The content tree, front first. See ShapeItem.

Text

Text on a transparent picture, laid out and placed by its style as a caption track’s cues are: its size and wrapping width fractions of the canvas, its anchor at style.position. The engine draws it with the fonts its host registered.

Fields

text: String

The text; \n starts a line. Non-empty, at most MAX_TEXT_CONTENT_BYTES bytes.

style: TextStyle

How it looks and where it lies. The font size is at most MAX_TEXT_GENERATOR_FONT_SIZE.

Implementations

impl Generator

pub fn is_valid(&self) -> bool

Whether every field is in range, as a project needs it to be.

pub fn validate(&self) -> Result<(), Option<ShapeIssue>>

Checks every field. A shapes generator’s problem names where in its tree it lies; another generator’s is None.

Errors

Returns the first problem, if any.

Trait Implementations

impl Clone for Generator

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 Generator

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Generator

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Generator

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for Generator

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
