Type of a Map. Maps to enum bpf_map_type in kernel uapi.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unknown

We choose to specify our own “unknown” type here b/c it’s really up to the kernel to decide if it wants to reject the map. If it accepts it, it just means whoever using this library is a bit out of date.

Implementations

impl MapType

pub fn is_percpu(&self) -> bool

Returns if the map is of one of the per-cpu types.

Trait Implementations

impl Clone for MapType

fn clone(&self) -> MapType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Display for MapType

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

Formats the value using the given formatter.

impl From<MapType> for u32

fn from(enum_value: MapType) -> Self

Converts to this type from the input type.

impl PartialEq<MapType> for MapType

fn eq(&self, other: &MapType) -> 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 !=.

impl TryFrom<u32> for MapType

type Error = TryFromPrimitiveError<MapType>

The type returned in the event of a conversion error.

fn try_from(number: u32) -> Result<Self, TryFromPrimitiveError<Self>>

Performs the conversion.

impl TryFromPrimitive for MapType

type Primitive = u32

const NAME: &'static str = _
