Struct ExcelError 

pub struct ExcelError {
    pub kind: ExcelErrorKind,
    pub message: Option<String>,
    pub context: Option<ErrorContext>,
    pub extra: ExcelErrorExtra,
}

The single struct your API passes around.

It combines:

• kind – the mandatory Excel error code
• message– optional human explanation
• context– generic location†
• extra – optional, kind-specific data

† If you never need row/col you can build the value with ExcelError::from(kind), which sets context = None.

Fields

kind: ExcelErrorKind

message: Option<String>

context: Option<ErrorContext>

extra: ExcelErrorExtra

Implementations

impl ExcelError

pub fn new(kind: ExcelErrorKind) -> ExcelError

Basic constructor (no message, no location, no extra).

pub fn with_message<S>(self, msg: S) -> ExcelError

where S: Into<String>,

Attach a human-readable explanation.

pub fn with_location(self, row: u32, col: u32) -> ExcelError

Attach generic row/column coordinates.

pub fn with_origin( self, sheet: Option<String>, row: u32, col: u32, ) -> ExcelError

Attach origin location where the error first occurred.

pub fn with_extra(self, extra: ExcelErrorExtra) -> ExcelError

Attach kind-specific extra data.

pub fn from_error_string(s: &str) -> ExcelError

pub fn new_value() -> ExcelError

pub fn new_name() -> ExcelError

pub fn new_div() -> ExcelError

pub fn new_ref() -> ExcelError

pub fn new_circ() -> ExcelError

pub fn new_num() -> ExcelError

pub fn new_na() -> ExcelError

Trait Implementations

impl Clone for ExcelError

fn clone(&self) -> ExcelError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExcelError

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

impl Eq for ExcelError

impl Error for ExcelError

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
