Enum Error 

pub enum Error {
    Unreadable(Error),
    Write(Error),
    Unmarked {
        cause: Error,
        content_removed: bool,
    },
}

Why a content file did not reach the session directory.

Variants

Unreadable(Error)

The content file could not be read out of the container: encrypted, stored with a compression method this build carries no decoder for, or a container declaring a version it does not implement.

Write(Error)

The content file could not be written.

Unmarked

Where the container came from could not be carried onto the content file, so opening the content file would not raise the warning opening the container would have.

Untested, and this says so rather than implying otherwise: reaching it needs a platform that gates opening on a mark and then refuses the write, which Linux does not do — it keeps provenance as a note. The arms that can be reached here are, and flow::open re-asks the filesystem before reporting content_removed, because the sentence has to be true when it is printed rather than when it was built.

Fields

cause: Error

What the carry reported.

content_removed: bool

Whether the content file was removed again. False means it is on disk and ungated, which the caller has to say out loud.

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 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>)
