Struct KeyId 

pub struct KeyId {
    bytes: [u8; 8],
    len: usize,
}

Key identifier

Fields

bytes: [u8; 8]

Byte array

len: usize

Length of byte array

Implementations

impl KeyId

pub const MAX_LEN: usize = Params::MAX_KEYID_LEN

Maximum length in bytes

pub const EMPTY: Self

Empty value.

pub fn new(slice: &[u8]) -> Result<Self>

Create a new KeyId from a slice.

Errors

Returns Error::KeyIdTooLong in event the provided slice is too long.

pub fn from_b64(s: &str) -> Result<Self>

Decode KeyId from a B64 string.

Errors

Returns Error::B64Encoding if the providing string couldn’t be decoded as B64.

pub fn as_bytes(&self) -> &[u8]

Borrow the inner value as a byte slice.

pub const fn len(&self) -> usize

Get the length in bytes.

pub const fn is_empty(&self) -> bool

Is this value empty?

Trait Implementations

impl AsRef<[u8]> for KeyId

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for KeyId

fn clone(&self) -> KeyId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeyId

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

Formats the value using the given formatter.

impl Default for KeyId

fn default() -> KeyId

Returns the “default value” for a type.

impl FromStr for KeyId

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self>

Parses a string s to return a value of this type.

impl Hash for KeyId

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 KeyId

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for KeyId

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for KeyId

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl TryFrom<&[u8]> for KeyId

type Error = Error

The type returned in the event of a conversion error.

fn try_from(bytes: &[u8]) -> Result<Self>

Performs the conversion.
