Enum Error 

pub enum Error {
    LockFailed,
    UnlockFailed,
    AllocationFailed,
}

Errors that can occur during memory operations.

Variants

LockFailed

Failed to lock memory (e.g., mlock or VirtualLock returned an error).

Common causes:

• RLIMIT_MEMLOCK is too low (Unix)
• The process lacks CAP_IPC_LOCK (Linux)
• The address space is too fragmented (Windows)

UnlockFailed

Failed to unlock memory (e.g., munlock or VirtualUnlock returned an error).

This is rare and usually indicates the memory was already unlocked or the address/size does not match a previous lock call.

AllocationFailed

Failed to allocate memory for a secret.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Error

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

Available on crate feature std only.

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

Available on crate feature std only.

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 PartialEq for Error

fn eq(&self, other: &Error) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
