Enum PersistedStateError 

pub enum PersistedStateError {
    Io {
        path: PathBuf,
        source: Error,
    },
    Parse(Error),
    UnsupportedFutureVersion {
        found: u32,
        supported: u32,
    },
}

Errors surfaced by the persisted-state loader.

Variants

Io

I/O failure reading the state file.

Fields

path: PathBuf

File path the daemon attempted to read.

source: Error

Underlying transport error.

Parse(Error)

JSON parse failure (top-level shape did not match either schema).

UnsupportedFutureVersion

format_version was present but greater than PersistedState::FORMAT_VERSION — the daemon refuses to downgrade-parse a forward-version state file.

Fields

found: u32

Version we read off disk.

supported: u32

Highest version this daemon understands.

Trait Implementations

impl Debug for PersistedStateError

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

Formats the value using the given formatter.

impl Display for PersistedStateError

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

Formats the value using the given formatter.

impl Error for PersistedStateError

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 From<Error> for PersistedStateError

fn from(source: Error) -> Self

Converts to this type from the input type.
