Struct Collection 

pub struct Collection<T> { /* private fields */ }

Marker value for a collection navigation.

Collection navigation fields are ignored by column metadata and start empty when an entity is materialized without an explicit include/load operation.

Implementations

impl<T> Collection<T>

pub const fn empty() -> Self

Creates an empty collection navigation.

pub fn from_vec(values: Vec<T>) -> Self

Creates a loaded collection navigation from existing values.

pub fn as_slice(&self) -> &[T]

Returns the loaded related entities.

Trait Implementations

impl<T: Clone> Clone for Collection<T>

fn clone(&self) -> Collection<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Collection<T>

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

Formats the value using the given formatter.

impl<T> Default for Collection<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: PartialEq> PartialEq for Collection<T>

fn eq(&self, other: &Collection<T>) -> 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.
