Struct bevy_ecs::storage::TableRow

pub struct TableRow(/* private fields */);

A opaque newtype for rows in Tables. Specifies a single row in a specific table.

Values of this type are retrievable from Archetype::entity_table_row and can be used alongside Archetype::table_id to fetch the exact table and row where an Entity’s

Values of this type are only valid so long as entities have not moved around. Adding and removing components from an entity, or despawning it will invalidate potentially any table row in the table the entity was previously stored in. Users should always fetch the appropriate row from the entity’s Archetype before fetching the entity’s components.

Implementations

impl TableRow

pub const fn from_u32(index: u32) -> Self

Creates a TableRow.

pub const fn from_usize(index: usize) -> Self

Creates a TableRow from a usize index.

Panics

Will panic if the provided value does not fit within a u32.

pub const fn as_usize(self) -> usize

Gets the index of the row as a usize.

pub const fn as_u32(self) -> u32

Gets the index of the row as a usize.

Trait Implementations

impl Clone for TableRow

fn clone(&self) -> TableRow

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TableRow

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

Formats the value using the given formatter.

impl PartialEq for TableRow

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