Enum hwlocality::object::depth::TypeToDepthError

pub enum TypeToDepthError {
    Nonexistent,
    Multiple,
    Unexpected(c_int),
}

Error from an hwloc query looking for the depth of a certain object type

Variants

Nonexistent

No object of the requested type exists in the topology

Multiple

Objects of the requested type exist at different depths in the topology

At the time of writing, this can only happen with ObjectType::Group.

Unexpected(c_int)

Unexpected special depth value or hwloc error

You can get this error for two different reasons:

• hwloc introduced a new virtual depth, and the version of the Rust bindings that you are using has not yet been updated to handle this new virtual depth. This is the most likely scenario.
• hwloc failed to probe the requested depth and returned a negative value to indicate that, but this negative value is not documented so the Rust bindings couldn’t figure out what’s going on.

Trait Implementations

impl Clone for TypeToDepthError

fn clone(&self) -> TypeToDepthError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TypeToDepthError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for TypeToDepthError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for TypeToDepthError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl Hash for TypeToDepthError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TypeToDepthError

fn eq(&self, other: &TypeToDepthError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
