Enum LoadError 

#[non_exhaustive]
pub enum LoadError {
    Json(Error),
    UnsupportedVersion {
        found: u32,
        supported: RangeInclusive<u32>,
    },
    OtherSymbol,
    NeedsHistory,
    NotClipboard,
    Skipped(Vec<SkippedDrawing>),
}

Why drawings were not loaded, by DrawingStorage::from_json, Chart::load_drawings or Chart::paste_drawings, before any drawing changed.

UnsupportedVersion above supported means a newer release wrote the data: keep it and update. Json means damaged 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.

Json(Error)

The text is not valid JSON, or its version, symbol, timeframe or metadata is missing or invalid.

UnsupportedVersion

The storage version is not one this release reads.

Fields

found: u32

The version the data declares.

supported: RangeInclusive<u32>

The versions this release reads.

OtherSymbol

The drawings belong to another symbol than the chart’s.

NeedsHistory

The chart has no bars to place the pasted anchors on; paste once history has loaded.

NotClipboard

The pasted text is not drawing clipboard text from Chart::copy_selected_drawings.

Skipped(Vec<SkippedDrawing>)

Drawings that could not be read, where every drawing is needed: a paste, or a document that automatic storage then never writes over.

Trait Implementations

impl Debug for LoadError

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

Formats the value using the given formatter.

impl Display for LoadError

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

Formats the value using the given formatter.

impl Error for LoadError

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.
