}

逐日波动率数据

Fields

time: String

交易日时间字符串

timestamp: Option<f64>

交易日时间戳

iv: Option<f64>

隐含波动率（该字段为百分比字段，默认不展示%，如20实际对应20%）

hv: Option<f64>

历史波动率（该字段为百分比字段，默认不展示%，如20实际对应20%）

underlying_price: Option<f64>

标的收盘价（当日为标记价）

pub fn iv(&self) -> f64

Returns the value of iv, or the default value if iv is unset.

pub fn hv(&self) -> f64

Returns the value of hv, or the default value if hv is unset.

pub fn underlying_price(&self) -> f64

Returns the value of underlying_price, or the default value if underlying_price is unset.

Trait Implementations

impl Clone for VolatilityItem

fn clone(&self) -> VolatilityItem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VolatilityItem

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

Formats the value using the given formatter.

impl Default for VolatilityItem

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for VolatilityItem

where VolatilityItem: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for VolatilityItem

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for VolatilityItem

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

impl Serialize for VolatilityItem

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
