Struct DbKey 

pub struct DbKey(/* private fields */);

Represents a key used for database entries.

Implementations

impl DbKey

pub const LEN: usize = 16usize

Represents the byte length.

pub const fn new() -> Self

Creates a new DbKey.

pub fn from_u64(val: u64) -> Self

Hashes input u64 for use as a database key.

pub fn from_slice(key: &[u8]) -> Self

Hashes input slice for use as a database key.

pub fn from_db(key: &[u8]) -> Self

Directly copies input database key.

pub const fn as_slice(&self) -> &[u8]

Gets a reference to the inner slice.

pub const fn len(&self) -> usize

Gets the DbKey length.

pub fn is_empty(&self) -> bool

Gets whether the DbKey is all zeroes.

Trait Implementations

impl AsMut<[u8]> for DbKey

fn as_mut(&mut self) -> &mut [u8]

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

impl AsRef<[u8]> for DbKey

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

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

impl Clone for DbKey

fn clone(&self) -> DbKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DbKey

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

Formats the value using the given formatter.

impl Default for DbKey

fn default() -> Self

Returns the “default value” for a type.

impl From<&[u8]> for DbKey

fn from(val: &[u8]) -> Self

Converts to this type from the input type.

impl<'d> From<&'d DbKey> for &'d [u8]

fn from(val: &'d DbKey) -> Self

Converts to this type from the input type.

impl PartialEq for DbKey

fn eq(&self, other: &DbKey) -> 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 Zeroize for DbKey

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.

impl Copy for DbKey

impl Eq for DbKey

impl StructuralPartialEq for DbKey
