Struct RowIdColumnDescriptor

pub struct RowIdColumnDescriptor {
    pub is_sorted: bool,
}

Describes the schema of the primary [RowId] column.

Fields

is_sorted: bool

Are the values in this column sorted?

false means either “unsorted” or “unknown”.

Implementations

impl RowIdColumnDescriptor

pub fn from_sorted(is_sorted: bool) -> Self

pub fn name(&self) -> &'static str

Human-readable name for this column.

pub fn to_arrow_field(&self) -> ArrowField

pub fn datatype(&self) -> ArrowDatatype

Trait Implementations

impl Clone for RowIdColumnDescriptor

fn clone(&self) -> RowIdColumnDescriptor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RowIdColumnDescriptor

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

Formats the value using the given formatter.

impl<'a> From<&'a RowIdColumnDescriptor> for ColumnDescriptorRef<'a>

fn from(desc: &'a RowIdColumnDescriptor) -> Self

Converts to this type from the input type.

impl Hash for RowIdColumnDescriptor

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 RowIdColumnDescriptor

fn cmp(&self, other: &RowIdColumnDescriptor) -> 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 RowIdColumnDescriptor

fn eq(&self, other: &RowIdColumnDescriptor) -> 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 RowIdColumnDescriptor

fn partial_cmp(&self, other: &RowIdColumnDescriptor) -> 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 TryFrom<&Field> for RowIdColumnDescriptor

type Error = WrongDatatypeError

The type returned in the event of a conversion error.

fn try_from(field: &ArrowField) -> Result<Self, Self::Error>

Performs the conversion.
