Enum DocumentError 

#[non_exhaustive]
pub enum DocumentError {
    NotFound(String),
    InvalidCursorContext(String),
    OutOfRange(String),
    InvalidArgument(String),
    Unsupported(String),
    Internal(Error),
}

Errors returned by the public text-document API.

The Display text is the original human-readable message; the variant carries the machine-matchable category. Marked #[non_exhaustive] so new categories can be added without breaking callers — match with a _ arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotFound(String)

A referenced entity (block, cell, document, …) does not exist.

InvalidCursorContext(String)

An operation was attempted with the cursor in the wrong structural context (e.g. a table operation while not inside a table).

OutOfRange(String)

An index or position was outside the valid range.

InvalidArgument(String)

The arguments were individually valid but invalid in combination (e.g. a selection spanning multiple frames, mismatched tables).

Unsupported(String)

The requested operation is not available in this build — e.g. crate::TextDocument::to_pdf called against a text-document build that did not enable the pdf cargo feature.

Internal(Error)

Any other error propagated from the backend layers.

Trait Implementations

impl Debug for DocumentError

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

Formats the value using the given formatter.

impl Display for DocumentError

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

Formats the value using the given formatter.

impl Error for DocumentError

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 From<Error> for DocumentError

fn from(source: Error) -> Self

Converts to this type from the input type.
