Implementations

impl Resource

pub fn create(
    name: &str,
    kind: ResourceKind,
    addr: usize,
    len: usize,
    flags: ResourceFlags
) -> Arc<Self>

Create a new Resource.

pub fn validate(&self, kind: ResourceKind) -> ZxResult

Validate the resource is the given kind or it is the root resource.

pub fn validate_ranged_resource(
    &self,
    kind: ResourceKind,
    addr: usize,
    len: usize
) -> ZxResult

Validate the resource is the given kind or it is the root resource, and [addr, addr+len] is within the range of the resource.

pub fn check_exclusive(&self, flags: ResourceFlags) -> ZxResult

Returns Err(ZxError::INVALID_ARGS) if the resource is not the root resource, and either it’s flags or parameter flags contains ResourceFlags::EXCLUSIVE.

pub fn get_info(&self) -> ResourceInfo

Get information of the resource.

fn related_koid(&self) -> KoID

If the object is related to another (such as the other end of a channel, or the parent of a job), returns the KoID of that object, otherwise returns zero.

fn allowed_signals(&self) -> Signal

Get object’s allowed signals.
