Trait Deps

pub trait Deps {
    const DEP_KIND_NULL: DepKind;
    const DEP_KIND_RED: DepKind;
    const DEP_KIND_MAX: u16;

    // Required methods
    fn with_deps<OP, R>(deps: TaskDepsRef<'_>, op: OP) -> R
       where OP: FnOnce() -> R;
    fn read_deps<OP>(op: OP)
       where OP: for<'a> FnOnce(TaskDepsRef<'a>);
}

Required Associated Constants

const DEP_KIND_NULL: DepKind

We use this for most things when incr. comp. is turned off.

const DEP_KIND_RED: DepKind

We use this to create a forever-red node.

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

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

where OP: FnOnce() -> R,

Execute the operation with provided dependencies.

fn read_deps<OP>(op: OP)

where OP: for<'a> FnOnce(TaskDepsRef<'a>),

Access dependencies from current implicit context.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl Deps for DepsType

const DEP_KIND_NULL: DepKind = dep_kinds::Null
