Trait EmptyBuilder 

pub trait EmptyBuilder {
    // Required methods
    fn empty() -> Self;
    fn with_capacity(capacity: usize) -> Self;
}

An octets builder that can be newly created empty.

Required Methods

fn empty() -> Self

Creates a new empty octets builder with a default size.

fn with_capacity(capacity: usize) -> Self

Creates a new empty octets builder with a suggested initial size.

The builder may or may not use the size provided by capacity as the initial size of the buffer. It may very well be possible that the builder is never able to grow to this capacity at all. Therefore, even if you create a builder for your data size via this function, appending may still fail.

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.
