Enum SettingsError 

pub enum SettingsError {
    Io(String),
    Serde(String),
    Opfs(String),
}

Errors from SettingsStore operations.

Both native and wasm32 impls use this single enum so call sites compile unchanged on either target.

Variants

Io(String)

I/O error (native only — file read/write/rename failures).

Serde(String)

JSON serialization or deserialization error.

Opfs(String)

OPFS error (wasm32 only — browser storage API failures).

Trait Implementations

impl Debug for SettingsError

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

Formats the value using the given formatter.

impl Display for SettingsError

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

Formats the value using the given formatter.

impl Error for SettingsError

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.
