Struct parquet::data_type::Int96

source ·
pub struct Int96 { /* private fields */ }
Expand description

Rust representation for logical type INT96, value is backed by an array of u32. The type only takes 12 bytes, without extra padding.

Implementations§

source§

impl Int96

source

pub fn new() -> Self

Creates new INT96 type struct with no data set.

source

pub fn data(&self) -> &[u32]

Returns underlying data as slice of u32.

source

pub fn set_data(&mut self, elem0: u32, elem1: u32, elem2: u32)

Sets data for this INT96 type.

source

pub fn to_i64(&self) -> i64

Converts this INT96 into an i64 representing the number of MILLISECONDS since Epoch

source

pub fn to_nanos(&self) -> i64

Converts this INT96 into an i64 representing the number of NANOSECONDS since EPOCH

Will wrap around on overflow

source

pub fn to_seconds_and_nanos(&self) -> (i64, i64)

Converts this INT96 to a number of seconds and nanoseconds since EPOCH
