Struct ModelError 

pub struct ModelError(/* private fields */);

Error returned by the row mutation functions of Model when the modification was not applied.

Implementations

impl ModelError

pub fn out_of_bounds(row_count: usize) -> Self

The row index is out of the model’s bounds. row_count is the model’s number of rows.

pub fn unsupported(model: &(impl Model + ?Sized)) -> Self

The model does not support this modification.

Trait Implementations

impl Clone for ModelError

fn clone(&self) -> ModelError

impl Eq for ModelError

impl Error for ModelError

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 ModelError

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

Equality operator ==.

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

Inequality operator !=.
