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§

fn type_name() -> &'static str

Returns a human-readable type name for the builder.

fn with_capacity(capacity: usize) -> Self

Creates a new builder with the given row capacity.

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

Appends a non-null string value to the builder.

fn append_null(&mut self)

Appends a null value to the builder.

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.
