Struct RawKey 

pub struct RawKey<K: Key> { /* private fields */ }

Raw table key.

Implementations

impl<K: Key> RawKey<K>

pub fn new(key: K) -> Self

Create new raw key.

pub const fn from_vec(vec: Vec<u8>) -> Self

Creates a raw key from an existing Vec. Useful when we already have the encoded key.

pub fn key(&self) -> Result<K, DatabaseError>

Returns the decoded value.

pub const fn raw_key(&self) -> &Vec<u8>

Returns the raw key as seen on the database.

pub fn into_key(self) -> Vec<u8>

Consumes Self and returns the inner raw key.

fn from(key: K) -> Self

Converts to this type from the input type.

impl<K: Hash + Key> Hash for RawKey<K>

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,

impl<K: Ord + Key> Ord for RawKey<K>

fn cmp(&self, other: &Self) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to #147781)

fn partial_cmp(&self, other: &Self) -> 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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
