Struct LayerLengthError 

pub struct LayerLengthError {
    pub id_family: IdFamily,
    pub required: usize,
    pub actual: usize,
}

A property layer shorter than the topology requires.

Carries the family, the required minimum row count, and the offending layer’s length; layout crates map this into their typed PropertyLayerTooShort build-error variant.

Performance

Copying this value is O(1).

Fields

id_family: IdFamily

Family whose layer fell short.

required: usize

Minimum row count the topology requires.

actual: usize

The offending layer’s actual length.

Trait Implementations

impl Clone for LayerLengthError

fn clone(&self) -> LayerLengthError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LayerLengthError

impl Debug for LayerLengthError

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

Formats the value using the given formatter.

impl Display for LayerLengthError

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

Formats the value using the given formatter.

impl Eq for LayerLengthError

impl Error for LayerLengthError

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 LayerLengthError

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