}

Fields

voter_pubkey: Pubkey

to whom the stake is delegated

stake: u64

activated stake amount, set at delegate() time

activation_epoch: u64

epoch at which this stake was activated, std::Epoch::MAX if is a bootstrap stake

deactivation_epoch: u64

epoch the stake was deactivated, std::Epoch::MAX if not deactivated

warmup_cooldown_rate: f64

👎Deprecated since 1.16.7: Please use solana_sdk::stake::state::warmup_cooldown_rate() instead

how much stake we can activate per-epoch as a fraction of currently effective stake

Trait Implementations

impl AbiExample for Delegation

fn example() -> Delegation

impl BorshDeserialize for Delegation

fn deserialize_reader<R>(reader: &mut R) -> Result<Delegation, Error>

where R: Read,

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 BorshDeserialize for Delegation

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

where __R: Read,

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 BorshSchema for Delegation

fn declaration() -> String

Get the name of the type without brackets.

fn add_definitions_recursively(definitions: &mut BTreeMap<String, Definition>)

Recursively, using DFS, add type definitions required for this type. Type definition partially explains how to serialize/deserialize a type.

impl BorshSchema for Delegation

fn declaration() -> String

Get the name of the type without brackets.

fn add_definitions_recursively(definitions: &mut HashMap<String, Definition>)

Recursively, using DFS, add type definitions required for this type. For primitive types this is an empty map. Type definition explains how to serialize/deserialize a type.

fn add_definition( declaration: String, definition: Definition, definitions: &mut HashMap<String, Definition> )

Helper method to add a single type definition to the map.

fn schema_container() -> BorshSchemaContainer

impl BorshSerialize for Delegation

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

where __W: Write,

impl BorshSerialize for Delegation

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

where W: Write,

fn try_to_vec(&self) -> Result<Vec<u8>, Error>

Serialize this instance into a vector of bytes.

impl Clone for Delegation

fn clone(&self) -> Delegation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Delegation

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

Formats the value using the given formatter.

impl Default for Delegation

fn default() -> Delegation

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Delegation

fn deserialize<__D>( __deserializer: __D ) -> Result<Delegation, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Delegation

fn eq(&self, other: &Delegation) -> 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.

impl Serialize for Delegation

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Delegation
