Struct Array

pub struct Array<'a> { /* private fields */ }

An SQL array.

An eXtremeDB SQL array contains Values of the same type, and exposes public methods to access them.

A Value can only be converted into an Array if it has the Array type. The opposite conversion is always possible.

Implementations

impl<'a> Array<'a>

pub fn elem_type(&self) -> Result<Type>

Returns the type of the array’s elements.

pub fn len(&self) -> Result<usize>

Returns the length of the array.

pub fn get_at(&self, at: usize) -> Result<Ref<'_>>

Returns the element at the given index.

Trait Implementations

impl<'a> From<Array<'a>> for Value<'a>

fn from(array: Array<'a>) -> Self

Converts to this type from the input type.

impl<'a> TryFrom<Value<'a>> for Array<'a>

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: Value<'a>) -> Result<Self, Self::Error>

Performs the conversion.
