Enum SaveError 

#[non_exhaustive]
pub enum SaveError {
    Serialize {
        path: PathBuf,
        source: Error,
    },
    Write {
        path: PathBuf,
        source: Error,
    },
    Inconsistent {
        reason: String,
    },
    Conflict {

        source: Error,
    },
}

Failure during Workspace::save.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Serialize

A TOML file failed to serialise.

Fields

path: PathBuf

source: Error

Write

Writing the serialised TOML to disk failed.

Fields

path: PathBuf

source: Error

Inconsistent

The workspace’s internal state was inconsistent at save time — usually a programmer error in the edit layer.

Fields

reason: String

Conflict

The file changed on disk since it was last loaded or saved. In-place editing (RFC 056) re-reads the text it mutates, so it notices this where the old rebuild-from-model path could not. Overwriting would silently discard whatever changed it made — the caller must reload and reapply instead.

Fields

path: PathBuf

Read

Re-reading a file to check it for external changes (RFC 056 §2 Q3, ahead of an in-place save) failed — permission denied, the file deleted out from under us, etc. Distinct from Conflict: this is “we couldn’t tell whether it changed,” not “we could tell, and it did.” Reloading — Conflict’s remedy — will not fix a permission error, so the two need different messages.

Fields

path: PathBuf

source: Error

Implementations

impl SaveError

pub fn kind(&self) -> SaveErrorKind

Trait Implementations

impl Debug for SaveError

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

Formats the value using the given formatter.

impl Display for SaveError

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

Formats the value using the given formatter.

impl Error for SaveError

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.
