Enum GraphError 

pub enum GraphError {
    NodeNotFound(u32),
    DuplicateNode(u32),
    CyclicEdge {
        from: u32,
        to: u32,
    },

        resource: String,
    },
    IncompatibleBinding {
        resource: String,
        node_kind: NodeKind,
    },
}

Errors produced by the compute graph.

Variants

NodeNotFound(u32)

A node with this ID does not exist.

DuplicateNode(u32)

A node with this ID has already been added.

CyclicEdge

Adding this edge would introduce a cycle.

Fields

from: u32

to: u32

CycleDetected

The graph contains a cycle (defensive check during ordering).

MissingBinding

A required resource binding is missing.

Fields

node_id: u32

resource: String

IncompatibleBinding

A resource is bound to an incompatible node type.

Fields

resource: String

node_kind: NodeKind

Trait Implementations

impl Clone for GraphError

fn clone(&self) -> GraphError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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 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 PartialEq for GraphError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
