Struct orc_format::proto::StringStatistics

pub struct StringStatistics {
    pub minimum: Option<String>,
    pub maximum: Option<String>,
    pub sum: Option<i64>,
}

Fields

minimum: Option<String>

maximum: Option<String>

sum: Option<i64>

sum will store the total length of all strings in a stripe

Implementations

impl StringStatistics

pub fn minimum(&self) -> &str

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

pub fn maximum(&self) -> &str

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

pub fn sum(&self) -> i64

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

Trait Implementations

impl Clone for StringStatistics

fn clone(&self) -> StringStatistics

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StringStatistics

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

Formats the value using the given formatter.

impl Default for StringStatistics

fn default() -> Self

Returns the “default value” for a type.

impl Message for StringStatistics

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, 

Encodes the message to a buffer.

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

Encodes the message to a newly allocated buffer.

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

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

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

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, 

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, 

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

impl PartialEq<StringStatistics> for StringStatistics

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
