Enum HugrError 

#[non_exhaustive]
pub enum HugrError {
    InvalidTag {
        required: OpTag,
        actual: OpTag,
    },
    InvalidPortDirection(Direction),
    UnsupportedEntrypoint {
        op: OpName,
    },
}

Errors that can occur while manipulating a Hugr.

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.

InvalidTag

The node was not of the required OpTag

Fields

required: OpTag

actual: OpTag

InvalidPortDirection(Direction)

An invalid port was specified.

UnsupportedEntrypoint

Cannot initialize a HUGR with the given entrypoint operation type.

Fields

op: OpName

The name of the unsupported operation.

Trait Implementations

impl Clone for HugrError

fn clone(&self) -> HugrError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HugrError

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

Formats the value using the given formatter.

impl Display for HugrError

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

Formats the value using the given formatter.

impl Error for HugrError

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<HugrError> for HUGRSerializationError

fn from(source: HugrError) -> Self

Converts to this type from the input type.

impl PartialEq for HugrError

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