}

Errors that can occur during graph construction.

Variants

UnexpectedToken

Token not valid in current state.

DuplicateDefinition(u16)

Attempted to define an ID that already exists.

UndefinedReference(u16)

Referenced an ID that hasn’t been defined yet.

IncompleteNode

Node definition was not completed (missing NodeEnd).

NoOutputs

Graph has no declared outputs.

MaxNodesExceeded(usize)

Maximum node count exceeded.

MaxDepthExceeded(usize)

Maximum graph depth exceeded.

MaxInputsExceeded(usize)

Maximum input count exceeded.

MaxOutputsExceeded(usize)

Maximum output count exceeded.

Trait Implementations

impl Clone for BuildError

fn clone(&self) -> BuildError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BuildError

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

Formats the value using the given formatter.

impl Display for BuildError

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

Formats the value using the given formatter.

impl Error for BuildError

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 BuildError

fn eq(&self, other: &BuildError) -> 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.
