Struct OffsetIndex 

pub struct OffsetIndex {
    pub page_locations: Vec<PageLocation>,
    pub unencoded_byte_array_data_bytes: Option<Vec<i64>>,
}

Optional offsets for each data page in a ColumnChunk.

Forms part of the page index, along with ColumnIndex.

OffsetIndex may be present even if ColumnIndex is not.

Fields

page_locations: Vec<PageLocation>

PageLocations, ordered by increasing PageLocation.offset. It is required that page_locations[i].first_row_index < page_locations[i+1].first_row_index.

unencoded_byte_array_data_bytes: Option<Vec<i64>>

Unencoded/uncompressed size for BYTE_ARRAY types.

See documention for unencoded_byte_array_data_bytes in SizeStatistics for more details on this field.

Implementations

impl OffsetIndex

pub fn new<F2>( page_locations: Vec<PageLocation>, unencoded_byte_array_data_bytes: F2, ) -> OffsetIndex

where F2: Into<Option<Vec<i64>>>,

Trait Implementations

impl Clone for OffsetIndex

fn clone(&self) -> OffsetIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OffsetIndex

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

Formats the value using the given formatter.

impl Hash for OffsetIndex

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for OffsetIndex

fn cmp(&self, other: &OffsetIndex) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for OffsetIndex

fn eq(&self, other: &OffsetIndex) -> 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 PartialOrd for OffsetIndex

fn partial_cmp(&self, other: &OffsetIndex) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TSerializable for OffsetIndex

fn read_from_in_protocol<T: TInputProtocol>( i_prot: &mut T, ) -> Result<OffsetIndex>

Reads the struct from the input Thrift protocol

fn write_to_out_protocol<T: TOutputProtocol>( &self, o_prot: &mut T, ) -> Result<()>

Writes the struct to the output Thrift protocol

impl Eq for OffsetIndex
