Implementations

impl IndexKeyPart

pub fn asc<S: Into<String>>(col: S, value_type: ValueType) -> Self

pub fn desc<S: Into<String>>(col: S, value_type: ValueType) -> Self

pub fn from_path( path: &PathExpr, direction: IndexDirection, value_type: ValueType, ) -> Self

Create from a PathExpr (handles multi-step paths)

pub fn full_path(&self) -> String

Full path as a flat string (e.g., “context.session_id”)

pub fn from_flat_path( path: &str, direction: IndexDirection, value_type: ValueType, ) -> Self

Create from a flat path string (e.g., “context.session_id”)

pub fn asc_path(path: &str, value_type: ValueType) -> Self

Create ascending keypart from flat path

pub fn desc_path(path: &str, value_type: ValueType) -> Self

Create descending keypart from flat path

Trait Implementations

impl Clone for IndexKeyPart

fn clone(&self) -> IndexKeyPart

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexKeyPart

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IndexKeyPart

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for IndexKeyPart

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 PartialEq for IndexKeyPart

fn eq(&self, other: &IndexKeyPart) -> 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 Serialize for IndexKeyPart

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
