Implementations

impl SnapError

pub fn dir_not_exists(path: PathBuf) -> Self

Creates a file system error for directory not existing

pub fn dir_create_failed(path: PathBuf) -> Self

Creates a file system error for directory creation failure

pub fn write_failed(path: PathBuf, kind: ErrorKind) -> Self

Creates a file system error for write failure

Trait Implementations

impl Debug for SnapError

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

Formats the value using the given formatter.

impl Display for SnapError

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

Formats the value using the given formatter.

impl Error for SnapError

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.
