Enum StorageError 

#[non_exhaustive]
pub enum StorageError {
    Read {
        symbol: String,
        error: LoadError,
    },
    Save {
        symbol: String,
        error: SaveError,
    },
    Storage(String),
}

A failed read or write of automatic drawing storage, from Chart::take_storage_error.

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.

Read

The stored drawings of symbol, or its kept copy, could not all be read. The document is kept and never written over; error tells a newer release from damaged data.

Fields

symbol: String

The symbol or kept copy whose document was read.

error: LoadError

Why it could not be read.

Save

The drawings of symbol could not be saved. They stay on the chart.

Fields

symbol: String

The symbol whose drawings were saved.

error: SaveError

Why they could not be saved.

Storage(String)

The storage service or a kept-copy operation failed; the message names it. A failed write keeps the drawings on the chart and is retried.

Trait Implementations

impl Debug for StorageError

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

Formats the value using the given formatter.

impl Display for StorageError

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

Formats the value using the given formatter.

impl Error for StorageError

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.
