Enum DrawingError 

#[non_exhaustive]
pub enum DrawingError {
    UnknownDrawing(usize),
    Locked(usize),
    NonFinitePrice {
        point: usize,
    },
    Invalid(&'static str),
}

Why Chart::create_drawing or Chart::set_drawing_points changed nothing.

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.

UnknownDrawing(usize)

No drawing has this id.

Locked(usize)

The drawing with this id is locked.

NonFinitePrice

The price of the anchor at this index, counted from 0, is NaN or infinite.

Fields

point: usize

The index of the anchor.

Invalid(&'static str)

The drawing manager refused the drawing; the text says why, such as a disabled or unknown tool or anchors the tool cannot use.

Trait Implementations

impl Clone for DrawingError

fn clone(&self) -> DrawingError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DrawingError

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

Formats the value using the given formatter.

impl Display for DrawingError

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

Formats the value using the given formatter.

impl Eq for DrawingError

impl Error for DrawingError

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 DrawingError

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

Equality operator ==.

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

Inequality operator !=.
