Enum EvalError 

#[non_exhaustive]
pub enum EvalError {
    InvalidProject(ModelError),
    UnmappableClip {
        clip: ClipId,
    },
    IncompleteComposition {
        clip: ClipId,
        composition: CompositionId,
        reason: PlanError,
    },
    IndexProjectMismatch {
        index_project: ProjectId,
        evaluated_project: ProjectId,
    },
}

An evaluator failure.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidProject(ModelError)

The input project violated a model invariant.

UnmappableClip

A valid range could not be represented during integer retiming.

Fields

clip: ClipId

Clip whose source timestamp could not be calculated.

IncompleteComposition

A visible clip’s composition cannot draw its output: it selects none, a node the output needs has an unconnected input, a group input no group node feeds is read, or a composition source reads a clip node (crate::PlanError’s incomplete reasons), or the composition nests or draws more than the planner holds.

Fields

clip: ClipId

The clip showing the composition.

composition: CompositionId

The composition.

reason: PlanError

What is missing.

IndexProjectMismatch

The reusable index belongs to a different project.

Fields

index_project: ProjectId

Project identity captured when the index was built.

evaluated_project: ProjectId

Project identity passed to evaluation.

Trait Implementations

impl Clone for EvalError

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 EvalError

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

Formats the value using the given formatter.

impl Display for EvalError

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

Formats the value using the given formatter.

impl Eq for EvalError

impl Error for EvalError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for EvalError

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

Equality operator ==.

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

Inequality operator !=.
