Enum LowerError

Why a step graph is not a program the engine runs.

Variants

Unexpected

An op other than the one the block expects next: where, what it is, and what was expected.

Fields

op: usize

kind: &'static str

block: String

expected: String

Ended

The step ended inside a block.

Fields

block: String

expected: String

Dataflow

An op reads a tensor other than the one the block’s dataflow says it reads.

Fields

op: usize

block: String

expected: String

found: String

Binding

A constant the checkpoint does not bind, or binds through a view the block does not read it by.

Fields

constant: String

why: String

Unsupported

A part of the model the engine has no unit for, by name.

Fields

layer: Option<usize>

what: String

Trailing

Ops left after the head.

Fields

op: usize

kind: &'static str

Trait Implementations

impl Clone for LowerError

fn clone(&self) -> LowerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LowerError

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

Formats the value using the given formatter.

impl Display for LowerError

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

Formats the value using the given formatter.

impl Error for LowerError

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 LowerError

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