Error type for this library, optionally implements std::error::Error.

Variants

AccessDenied

The keyring wasn’t available for modification by the user.

QuotaExceeded

The key quota for this user would be exceeded by creating this key or linking it to the keyring.

BadAddress

One or more of type, description, and payload points outside process’s accessible address space.

InvalidArguments

Provided bad arguments

KeyExpired

The keyring has expired.

KeyRevoked

The keyring has been revoked.

KeyRejected

The attempt to generate a new key was rejected.

KeyringDoesNotExist

The keyring doesn’t exist.

KeyDoesNotExist

They key does not exist

OutOfMemory

Insufficient memory to create a key.

InvalidDescription

Invalid Description

InvalidIdentifier

An invalid identifier was returned

OperationNotSupported

Operation not supported

WriteError

Write to destination failed

Unknown(i32)

Unknown - catch all, return this instead of panicing

Implementations

impl KeyError

pub fn from_errno() -> KeyError

Obtain the KeyError derived from checking errno

Trait Implementations

impl Clone for KeyError

fn clone(&self) -> KeyError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KeyError

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

Formats the value using the given formatter.

impl Display for KeyError

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

Formats the value using the given formatter.

impl Hash for KeyError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for KeyError

fn cmp(&self, other: &KeyError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<KeyError> for KeyError

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<KeyError> for KeyError

fn partial_cmp(&self, other: &KeyError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
