Public error type for NIR operations.

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.

Unimplemented(&'static str)

Feature not yet implemented.

Returned by HDF5 I/O function stubs when the hdf5 feature is not enabled.

UnknownNodeType(String)

HDF5 / wire type string is not a known NIR node.

DuplicateNode(String)

A node name was inserted twice into the same graph.

MissingNode(String)

An edge or lookup referenced a node name that is not in the graph.

DuplicateEdge(String, String)

The same directed edge (src, dst) appears more than once.

InvalidGraph(String)

Structural or semantic problem with a graph that is not covered above.

UnsupportedVersion(String)

NIR file / graph version is not supported by this crate.

MissingField(String)

A required wire field was absent when decoding a node or graph.

InvalidTensor(String)

Tensor shape / data length mismatch or other tensor invariant failure.

ReadLimitExceeded

A bounded read would exceed its decoded-allocation budget.

Fields

context: String

Dataset or synthesized field being charged.

limit: usize

Configured decoded-allocation limit in bytes.

used: usize

Bytes already charged by earlier allocations.

requested: usize

Bytes requested by the allocation that was rejected.

Io(String)

Filesystem or HDF5 library failure while reading or writing a .nir file.

The underlying hdf5::Error is rendered into the message rather than carried, so NirError stays Clone + Eq.

Trait Implementations

impl Clone for NirError

fn clone(&self) -> NirError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NirError

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

Formats the value using the given formatter.

impl Display for NirError

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

Formats the value using the given formatter.

impl Eq for NirError

impl Error for NirError

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 NirError

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

Equality operator ==.

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

Inequality operator !=.
