Struct KvKey 

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

Key type for stupid-simple-kv. Must be order-preserving (lexicographically).

Implementations

impl KvKey

pub fn new() -> Self

pub fn push(&mut self, part: &dyn KeySegment)

pub fn starts_with(&self, key: &KvKey) -> bool

pub fn successor(&self) -> Option<KvKey>

Returns the smallest key that is strictly greater than this one. Useful for exclusive upper bounds in range queries.

Trait Implementations

impl Clone for KvKey

fn clone(&self) -> KvKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KvKey

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

Formats the value using the given formatter.

impl Default for KvKey

fn default() -> Self

Returns the “default value” for a type.

impl IntoKey for KvKey

fn to_key(&self) -> KvKey

impl Ord for KvKey

fn cmp(&self, other: &KvKey) -> 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 KvKey

fn eq(&self, other: &KvKey) -> 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 KvKey

fn partial_cmp(&self, other: &KvKey) -> 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.
