Trait ValueWriter

Source 
pub trait ValueWriter: Default {
    type Value;

    // Required methods
    fn write(&mut self, val: &Self::Value);
    fn serialize_block(&self, output: &mut Vec<u8>);
    fn clear(&mut self);
}
Expand description

ValueWriter is a trait to make it possible to write blocks of value.

Required Associated Types§

Source

type Value

Type of the value being written.

Required Methods§

Source

fn write(&mut self, val: &Self::Value)

Records a new value. This method usually just accumulates data in a Vec, only to be serialized on the call to ValueWriter::serialize_block.

Source

fn serialize_block(&self, output: &mut Vec<u8>)

Serializes the accumulated values into the output buffer.

Source

fn clear(&mut self)

Clears the ValueWriter. After a call to clear, the ValueWriter should behave like a fresh ValueWriter::default().

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.
