Struct RowValues 

pub struct RowValues { /* private fields */ }

Column-value map for one relational read-model row.

Implementations

pub fn insert( &mut self, column: impl Into<String>, value: RowValue, ) -> Option<RowValue>

pub fn insert_serde<T: Serialize + ?Sized>( &mut self, column: impl Into<String>, value: &T, ) -> Result<Option<RowValue>, ReadModelError>

pub fn get(&self, column: &str) -> Option<&RowValue>

pub fn contains_key(&self, column: &str) -> bool

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn get_serde<T: DeserializeOwned>( &self, column: &str, ) -> Result<T, ReadModelError>

pub fn iter(&self) -> impl Iterator<Item = (&str, &RowValue)>

Trait Implementations

impl Clone for RowValues

fn clone(&self) -> RowValues

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RowValues

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

Formats the value using the given formatter.

impl Default for RowValues

fn default() -> RowValues

Returns the “default value” for a type.

impl IntoIterator for RowValues

type Item = (String, RowValue)

The type of the elements being iterated over.

type IntoIter = IntoIter<String, RowValue>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for RowValues

fn eq(&self, other: &RowValues) -> 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.
