Struct dynamodb_expression::key::Key

pub struct Key { /* private fields */ }

Used to build a key condition expression.

An instance can be constructed using the Path::key method, or the From<Into<Path>> implementation.

Implementations

impl Key

pub fn begins_with<T>(self, prefix: T) -> KeyConditionwhere T: Into<StringOrRef>,

pub fn between<L, U>(self, lower: L, upper: U) -> KeyConditionwhere L: Into<Operand>, U: Into<Operand>,

pub fn equal<T>(self, right: T) -> KeyConditionwhere T: Into<Operand>,

pub fn greater_than<T>(self, right: T) -> KeyConditionwhere T: Into<Operand>,

pub fn greater_than_or_equal<T>(self, right: T) -> KeyConditionwhere T: Into<Operand>,

pub fn less_than<T>(self, right: T) -> KeyConditionwhere T: Into<Operand>,

pub fn less_than_or_equal<T>(self, right: T) -> KeyConditionwhere T: Into<Operand>,

Trait Implementations

impl Clone for Key

fn clone(&self) -> Key

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Key

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

Formats the value using the given formatter.

impl<T> From<T> for Keywhere T: Into<Path>,

fn from(path: T) -> Self

Convert something that implements Into<Path> into a Key.

impl Hash for Key

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 Key

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Key

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for Key

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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