Struct FeaturesSet 

pub struct FeaturesSet(/* private fields */);

Bit map of supported features

Implementations

impl FeaturesSet

pub fn activate(self, feature: Feature) -> Self

Enables given feature in featureset

pub fn contains(&mut self, feature: Feature) -> bool

Returns true if given featureset has requested feature enabled

Trait Implementations

impl BorshDeserialize for FeaturesSet

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for FeaturesSet

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for FeaturesSet

fn clone(&self) -> FeaturesSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FeaturesSet

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

Formats the value using the given formatter.

impl Default for FeaturesSet

fn default() -> FeaturesSet

Returns the “default value” for a type.

impl PartialEq for FeaturesSet

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

Tests for self and other values to be equal, and is used by ==.

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

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