Why logic was not pipelined.

Variants

Sequential

The graph holds registers already: it is pipelined from combinational logic.

EdgeTooDeep

An edge is deeper than the period by itself, and no register splits an edge.

Fields

edge: usize

delay: i64

LatencyTooShort

The latency is too short for the period: the least that is enough.

Fields

minimum: i64

Uncuttable

Logic deeper than the period with nowhere the policy allows a register, at any latency: the nets around the loop of constraints that says so.

Fields

through: Vec<String>

NegativeLatency

The latency is negative.

CombinationalLoop

The logic loops through no register.

Unbalanced

The paths into a node hold different numbers of registers: not a pipeline, whose every path from its inputs to a node holds as many.

Fields

node: String

Held

A register with more than its data in (an enable, a reset, a memory’s port): state, not a pipeline’s stage.

Fields

register: String

Boxed

An instance of a module timed apart: its logic, and any loop through it, is not the graph’s.

Fields

cell: String

Flow(FlowError)

Trait Implementations

impl Clone for PipeError

fn clone(&self) -> PipeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PipeError

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

Formats the value using the given formatter.

impl Display for PipeError

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

Formats the value using the given formatter.

impl Error for PipeError

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 PipeError

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