pub struct ResMut<'a, T: Component> { /* private fields */ }Expand description
Mutable borrow of a singleton resource T.
Obtained as a system parameter; derefs to T.

fn requires() -> Vec<RequiredResource>
Resource types this parameter unconditionally needs present to avoid
panicking. Used by
App to validate — before
running a non-convergent stage’s systems — that every hard
requirement is already satisfied, failing fast with a clear message
instead of panicking deep inside whichever system happens to run
first. Read moreAuto Trait Implementations§
