Enum Error 

pub enum Error {
    Inactive,
    Io {
        action: String,
        path: Option<PathBuf>,
        source: Error,
    },
    NotRelative {
        path: PathBuf,
    },
    Escapes {
        path: PathBuf,
    },
    Other(Box<dyn StdError + Send + Sync>),
}

Errors returned by Environment operations.

Display is one line by default; the alternate form ({error:#}) appends the underlying cause chain, so wrapped std::io::Errors surface their real reason.

Variants

Inactive

A method that requires an active sandbox was called outside of Environment::run.

Io

A filesystem or environment operation failed. action describes what was attempted and path names the target when there is one.

Fields

action: String

What was being attempted, e.g. "create the file".

path: Option<PathBuf>

The target path, when the failing operation had one.

source: Error

The underlying cause.

NotRelative

A create_* / write_file path was absolute; sandbox paths must be relative.

Fields

path: PathBuf

The offending path.

Escapes

A path resolved outside the sandbox directory (e.g. it contained a .. component).

Fields

path: PathBuf

The offending path.

Other(Box<dyn StdError + Send + Sync>)

A user error ?-converted from inside a run closure.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn StdError + '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<Box<dyn Error + Sync + Send>> for Error

fn from(source: Box<dyn StdError + Send + Sync>) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
