Struct flatbox_ecs::Context
source · pub struct Context<'a> { /* private fields */ }Expand description
Holds all data necessary for the execution of the world. The data is held by references, and needs to outlive the context itself
Implementations§
source§impl<'a> Context<'a>
impl<'a> Context<'a>
sourcepub fn new(data: &'a dyn Data) -> Context<'a>
pub fn new(data: &'a dyn Data) -> Context<'a>
Construct a new context from the tuple of references data
sourcepub fn borrow<T>(&'a self) -> Result<<T as ContextBorrow<'a>>::Target, Error>where
T: ContextBorrow<'a>,
pub fn borrow<T>(&'a self) -> Result<<T as ContextBorrow<'a>>::Target, Error>where
T: ContextBorrow<'a>,
Borrows data of type T from the context. Does not panic.
sourcepub fn cell<T>(&'a self) -> Result<&'a AtomicRefCell<NonNull<u8>>, Error>where
T: IntoAccess,
pub fn cell<T>(&'a self) -> Result<&'a AtomicRefCell<NonNull<u8>>, Error>where
T: IntoAccess,
Returns the cell associated to T.
Note: Types are erased, but casting is guaranteed to be correct.

source§fn to_subset(&self) -> Option<SS>
fn to_subset(&self) -> Option<SS>
The inverse inclusion map: attempts to construct
self from the equivalent element of its
superset. Read moresource§fn is_in_subset(&self) -> bool
fn is_in_subset(&self) -> bool
Checks if
self is actually part of its subset T (and can be converted to it).source§fn to_subset_unchecked(&self) -> SS
fn to_subset_unchecked(&self) -> SS
Use with care! Same as
self.to_subset but without any property checks. Always succeeds.source§fn from_subset(element: &SS) -> SP
fn from_subset(element: &SS) -> SP
The inclusion map: converts
self to the equivalent element of its superset.
