    pub val: Option<ScalarValue>,
}

Fields

Implementations

impl Precision

pub fn precision_info(&self) -> PrecisionInfo

Returns the enum value of precision_info, or the default if the field is set to an invalid enum value.

pub fn set_precision_info(&mut self, value: PrecisionInfo)

Sets precision_info to the provided enum value.

Trait Implementations

impl Clone for Precision

fn clone(&self) -> Precision

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Precision

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

Formats the value using the given formatter.

impl Default for Precision

fn default() -> Self

Returns the “default value” for a type.

impl From<&Precision<ScalarValue>> for Precision

fn from(s: &Precision<ScalarValue>) -> Precision

Converts to this type from the input type.

impl From<&Precision<usize>> for Precision

fn from(s: &Precision<usize>) -> Precision

Converts to this type from the input type.

impl From<Precision> for Precision<ScalarValue>

fn from(s: Precision) -> Self

Converts to this type from the input type.

impl From<Precision> for Precision<usize>

fn from(s: Precision) -> Self

Converts to this type from the input type.

impl Message for Precision

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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

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

where B: Buf, Self: Default,

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

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

where B: Buf, Self: Sized,

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

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

where B: Buf, Self: Sized,

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

impl PartialEq for Precision

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