Enum ValidateError 

pub enum ValidateError {
    SlotConflict {
        a: ValueId,
        b: ValueId,
        slot: SlotId,
    },
    UndersizedSlot {
        value: ValueId,

    },
    Cycle,
}

A violated correctness invariant found by crate::validate.

Variants

SlotConflict

Two values with overlapping live intervals were assigned the same slot — one would clobber the other’s still-live data.

Fields

a: ValueId

b: ValueId

slot: SlotId

UndersizedSlot

A value is assigned to a slot too small to hold it.

Fields

value: ValueId

slot: SlotId

needed: usize

capacity: usize

MissingAssignment

A buffer owner has no slot assignment in the plan.

Fields

value: ValueId

UnknownSlot

A value is assigned to a slot id that does not exist in the plan.

Fields

value: ValueId

slot: SlotId

ViewOutlivesSource

A zero-copy view outlives the source buffer it aliases (fold error): the source could be recycled while the view still points into it.

Fields

view: ValueId

source_owner: ValueId

view_use: usize

source_end: usize

Cycle

The graph became unschedulable between planning and validation.

Trait Implementations

impl Clone for ValidateError

fn clone(&self) -> ValidateError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ValidateError

impl Debug for ValidateError

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

Formats the value using the given formatter.

impl Display for ValidateError

impl Eq for ValidateError

impl Error for ValidateError

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 ValidateError

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

Equality operator ==.

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

Inequality operator !=.
