Trait for string-like array builders

This trait provides unified interface for builders that append string-like data such as GenericStringBuilder<O> and crate::builder::StringViewBuilder

Required Methods§

Source

fn append_value(&mut self, value: &str)

Appends a non-null string value to the builder.

Source

fn append_null(&mut self)
