Trait StringArrayType

pub trait StringArrayType<'a>: ArrayAccessor<Item = &'a str> + Sized {
    // Required methods
    fn is_ascii(&self) -> bool;
    fn iter(&self) -> ArrayIter<Self>;
}

A trait for Arrow String Arrays, currently three types are supported:

• StringArray
• LargeStringArray
• StringViewArray

This trait helps to abstract over the different types of string arrays so that we don’t need to duplicate the implementation for each type.

Required Methods

fn is_ascii(&self) -> bool

Returns true if all data within this string array is ASCII

fn iter(&self) -> ArrayIter<Self>

Constructs a new iterator

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
