Implementations

impl Tag

pub fn auto(time: SystemTime, exists: impl Fn(&[u8]) -> bool) -> Self

Create a new tag that does not exist yet.

Trait Implementations

impl Borrow<[u8]> for Tag

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

Immutably borrows from an owned value.

impl Clone for Tag

fn clone(&self) -> Tag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Tag

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Tag

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Tag

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

Formats the value using the given formatter.

impl From<&str> for Tag

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<Bytes> for Tag

fn from(value: Bytes) -> Self

Converts to this type from the input type.

impl From<String> for Tag

fn from(value: String) -> Self

Converts to this type from the input type.

impl From<Tag> for Bytes

fn from(value: Tag) -> Self

Converts to this type from the input type.

impl Key for Tag

fn compare(data1: &[u8], data2: &[u8]) -> Ordering

Compare data1 with data2

impl Ord for Tag

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

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

fn partial_cmp(&self, other: &Tag) -> 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 RedbKey for Tag

fn compare(data1: &[u8], data2: &[u8]) -> Ordering
