Enum PlanError

Why a composition’s output cannot be drawn.

Variants

NoOutput

The composition selects no output.

MissingInput

A node the output needs has an unconnected input.

Fields

node: NodeId

The node.

input: String

The input: input, from, to, matte, layers[i], inputs[i], or inputs.<name>.

UnboundGroupInput

A group input read where no group node feeds it: in a composition drawn as a clip’s composition or as a source.

Fields

node: NodeId

The node.

ClipWithoutClip

A clip node in a composition drawn as a source, which shows no clip.

Fields

node: NodeId

The node.

NestedTooDeep

The group or media node draws compositions nested deeper than alpha2_model::MAX_COMPOSITION_DEPTH. Validation refuses such a project, so only an unvalidated one reaches this.

Fields

node: NodeId

The node.

TooLarge

The output needs more than alpha2_model::MAX_INLINED_NODES steps, which validation refuses, or the plans of the project hold more than MAX_PLAN_BYTES.
