Enum SecretError 

#[non_exhaustive]
pub enum SecretError {
    Io(Error),
    Decode(Error),
    InvalidKey(String),
    InvalidEnvironment(String),
    ValueTooLong {
        key: String,
        len: usize,
    },
    FutureVersion(u32),
}

Error type returned by this module.

#[non_exhaustive]: shep-core is published, so a new failure variant must not break an out-of-tree match.

Wraps io::Error/serde_json::Error directly rather than stringifying them, matching crate::kv::KvError, so callers keep the underlying diagnostic through core::error::Error::source; this type does not derive Clone/PartialEq/Eq as a result.

No variant carries a secret’s value: a message names the key, the namespace or the environment, and nothing else.

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.

Io(Error)

The store could not be read, written, or replaced.

Decode(Error)

The store’s JSON could not be parsed.

Refused rather than repaired: a partial read would silently drop credentials still on disk, and a later write would erase them.

InvalidKey(String)

A key outside the grammar; carries it verbatim so the message can quote what was typed.

InvalidEnvironment(String)

An environment name outside the grammar; carries it verbatim.

ValueTooLong

A value over MAX_VALUE_BYTES.

Fields

key: String

The key it was being stored under.

len: usize

Its length in bytes.

FutureVersion(u32)

The store on disk is a version this build does not understand; carries that version. Nothing was written.

Trait Implementations

impl Debug for SecretError

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

Formats the value using the given formatter.

impl Display for SecretError

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

Formats the value using the given formatter.

impl Error for SecretError

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 SecretError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for SecretError

fn from(source: Error) -> Self
