Enum GraphError 

#[non_exhaustive]
pub enum GraphError {
    InvalidDependency,
    MissingOutput,
    SourceOutput,
    EffectKindMismatch,
    Render(RenderError),
}

Structural or execution failure in a render graph.

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.

InvalidDependency

A node references an ID not already present in the graph.

MissingOutput

No final output node was selected.

SourceOutput

An external source cannot be returned as an owned render result.

EffectKindMismatch

A registered shader kind does not match its graph node.

Render(RenderError)

A rendering operation failed.

Implementations

impl GraphError

pub const fn into_render_error(self) -> RenderError

Collapses a graph failure into the renderer’s error type, reporting every structural fault as RenderError::InvalidGraph.

Trait Implementations

impl Clone for GraphError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for GraphError

impl Debug for GraphError

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

Formats the value using the given formatter.

impl Display for GraphError

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

Formats the value using the given formatter.

impl Eq for GraphError

impl Error for GraphError

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 From<RenderError> for GraphError

fn from(error: RenderError) -> Self

Converts to this type from the input type.

impl PartialEq for GraphError

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

Equality operator ==.

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

Inequality operator !=.
