// Required methods
fn with_deps<OP, R>(deps: TaskDepsRef<'_>, op: OP) -> R

Required Associated Constants§
sourceconst DEP_KIND_NULL: DepKind
const DEP_KIND_NULL: DepKind
We use this for most things when incr. comp. is turned off.
sourceconst DEP_KIND_RED: DepKind
const DEP_KIND_RED: DepKind
We use this to create a forever-red node.
sourceconst DEP_KIND_MAX: u16
const DEP_KIND_MAX: u16
This is the highest value a DepKind
can have. It’s used during encoding to
pack information into the unused bits.
Required Methods§
sourcefn with_deps<OP, R>(deps: TaskDepsRef<'_>, op: OP) -> Rwhere
OP: FnOnce() -> R,
fn with_deps<OP, R>(deps: TaskDepsRef<'_>, op: OP) -> Rwhere
OP: FnOnce() -> R,
Execute the operation with provided dependencies.
sourcefn read_deps<OP>(op: OP)where
OP: for<'a> FnOnce(TaskDepsRef<'a>),
fn read_deps<OP>(op: OP)where
OP: for<'a> FnOnce(TaskDepsRef<'a>),
Access dependencies from current implicit context.
Object Safety§
This trait is not object safe.
