Enum hard::HardError

pub enum HardError {
    AllocationFailed(Errno),
    MprotectNoAccessFailed(Errno),
    MprotectReadOnlyFailed(Errno),
    MprotectReadWriteFailed(Errno),
    InitFailed,
}

Represents an error encountered while using Hard.

Variants

AllocationFailed(Errno)

Tuple Fields

0: Errno

sodium_malloc returned an error when we tried to allocate a region of memory.

This is most likely to occur if there is not sufficient memory to allocate, but could occur for other reasons. The associated value contains the value of the errno value, which is set if sodium_malloc fails.

MprotectNoAccessFailed(Errno)

Tuple Fields

0: Errno

sodium_mprotect_noaccess returned an error.

This is most likely to occur if the platform we’re running on doesn’t have the mprotect syscall (or its equivalent).

MprotectReadOnlyFailed(Errno)

Tuple Fields

0: Errno

sodium_mprotect_readonly returned an error.

This is most likely to occur if the platform we’re running on doesn’t have the mprotect syscall (or its equivalent).

MprotectReadWriteFailed(Errno)

Tuple Fields

0: Errno

sodium_mprotect_readwrite returned an error.

This is most likely to occur if the platform we’re running on doesn’t have the mprotect syscall (or its equivalent).

InitFailed

sodium_init returned an error.

Trait Implementations

impl Clone for HardError

fn clone(&self) -> HardError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HardError

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

Formats the value using the given formatter.

impl Display for HardError

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

Formats the value using the given formatter.

impl Error for HardError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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

impl PartialEq<HardError> for HardError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
