Enum SkipReason 

#[non_exhaustive]
pub enum SkipReason {
    UnknownTool(ParseToolTypeError),
    Cursor {
        tool: DrawingToolType,
    },
    MissingAnchors {
        tool: DrawingToolType,
        anchors: usize,
        needed: usize,
    },
    DuplicateId {
        id: String,
    },
    Invalid(Error),
}

Why DrawingStorage::from_json left a drawing out.

An UnknownTool in a file of version 2 or later was most likely written by a newer release that added the tool: keep the file. The other reasons describe damaged or hand-edited data.

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.

UnknownTool(ParseToolTypeError)

The tool is not one this release knows; ParseToolTypeError::input holds its name.

Cursor

The tool is a cursor, such as the eraser, which creates no drawing.

Fields

tool: DrawingToolType

The cursor tool.

MissingAnchors

The drawing has fewer anchors than its tool draws with.

Fields

tool: DrawingToolType

The tool of the drawing.

anchors: usize

The anchors the drawing has.

needed: usize

The anchors the tool needs.

DuplicateId

An earlier drawing in the file has the same id; the first one is loaded.

Fields

id: String

The repeated id.

Invalid(Error)

A field is missing or has the wrong type, or a value is out of range, such as a null written for a non-finite number, a timestamp outside the supported range or a setting out of bounds.

Trait Implementations

impl Debug for SkipReason

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

Formats the value using the given formatter.

impl Display for SkipReason

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

Formats the value using the given formatter.

impl Error for SkipReason

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.
