Enum Unplaceable 

pub enum Unplaceable {
    MissingCapability {
        needed: Capability,
        target: &'static str,
    },
    TooSmall {
        needed_rows: usize,
        needed_cols: usize,
        target_rows: usize,
        target_cols: usize,
        target: &'static str,
    },
}

Why a program cannot be placed on a given target — a TYPED refusal, never a silently-wrong grid.

Variants

MissingCapability

The target lacks a capability the program needs; needed names exactly what is missing.

Fields

needed: Capability

target: &'static str

TooSmall

The placed dataflow is larger than the described array.

Fields

needed_rows: usize

needed_cols: usize

target_rows: usize

target_cols: usize

target: &'static str

Trait Implementations

impl Clone for Unplaceable

fn clone(&self) -> Unplaceable

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Unplaceable

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

Formats the value using the given formatter.

impl PartialEq for Unplaceable

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