Enum VirtualizerError 

pub enum VirtualizerError {
    InvalidItemCount(String),
    InvalidItemSize(String),
    InvalidOverscan(String),
    IndexOutOfBounds {
        requested: usize,
        total: usize,
    },
    MeasurementError(String),
    ScrollContainerUnavailable(String),
    InvalidConfiguration(String),
}

Errors that can occur during virtualizer operations.

Covers all failure modes in the virtualization engine, including invalid configuration, measurement issues, scroll container problems, and index-related errors.

Variants

InvalidItemCount(String)

The provided item count is invalid.

Details

• Occurs when the item count overflows internal calculations.

InvalidItemSize(String)

The provided item size is invalid.

Details

• Occurs when a zero or negative size is specified.

InvalidOverscan(String)

The overscan value is invalid.

Details

• Occurs when overscan is negative.

IndexOutOfBounds

The requested index is out of bounds.

Details

• Occurs when scrolling to or measuring an item beyond the dataset.

Fields

requested: usize

The index that was requested.

total: usize

The total number of items.

MeasurementError(String)

A measurement update failed.

Details

• Occurs when a measured size is invalid (e.g., negative or NaN).

ScrollContainerUnavailable(String)

The scroll container reference is unavailable.

Details

• Occurs when the DOM element for the scroll container cannot be accessed.

InvalidConfiguration(String)

A configuration parameter is invalid.

Details

• Occurs for general configuration issues not covered by more specific variants.

Trait Implementations

impl Clone for VirtualizerError

fn clone(&self) -> VirtualizerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VirtualizerError

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

Formats the value using the given formatter.

impl Display for VirtualizerError

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

Formats the value using the given formatter.

impl Error for VirtualizerError

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 VirtualizerError

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