Struct mz_repr::adt::array::ArrayDimension

pub struct ArrayDimension {
    pub lower_bound: isize,
    pub length: usize,
}

The specification of one dimension of an Array.

Fields

lower_bound: isize

The “logical” index at which this dimension begins. This value has no bearing on the physical layout of the data, only how users want to use its indices (which may be negative).

length: usize

The number of elements in this array.

Implementations

impl ArrayDimension

pub fn dimension_bounds(&self) -> (isize, isize)

Presents the “logical indices” of the array, i.e. those that are revealed to the user.

Panics

• If the array contain more than isize::MAX elements (i.e. more than 9EB of data).

Trait Implementations

impl Clone for ArrayDimension

fn clone(&self) -> ArrayDimension

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ArrayDimension

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

Formats the value using the given formatter.

impl FixedSizeCodec<ArrayDimension> for PackedArrayDimension

const SIZE: usize = 16usize

Number of bytes the encoded format requires.

fn as_bytes(&self) -> &[u8]

Returns the encoded bytes as a slice.

fn from_bytes(slice: &[u8]) -> Result<Self, String>

Create an instance of self from a slice.

fn from_value(value: ArrayDimension) -> Self

Encode a type of T into this format.

fn into_value(self) -> ArrayDimension

Decode an instance of T from this format.

impl Hash for ArrayDimension

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 ArrayDimension

fn cmp(&self, other: &ArrayDimension) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ArrayDimension

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

fn partial_cmp(&self, other: &ArrayDimension) -> 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.
