Trait CompressedArray 

pub trait CompressedArray {
    const MAX_FOR_UNUSED: bool = false;

    // Required methods
    fn new(
        values: Vec<usize>,
        last_in_value: usize,
        number_of_keys: usize,
    ) -> Self;
    fn get(&self, index: usize) -> usize;
    fn write(&self, output: &mut dyn Write) -> Result<()>;
    fn write_bytes(&self) -> usize;
    fn read(input: &mut dyn Read) -> Result<Self>
       where Self: Sized;
}

Compressed array of usize integers that can be used by PHast.

Provided Associated Constants

const MAX_FOR_UNUSED: bool = false

Expect values to have usize::MAX for unused values; false if values must be sorted.

Required Methods

fn new(values: Vec<usize>, last_in_value: usize, number_of_keys: usize) -> Self

Construct Self.

fn get(&self, index: usize) -> usize

Get index-th item from the array.

fn write(&self, output: &mut dyn Write) -> Result<()>

Writes self to the output.

fn write_bytes(&self) -> usize

Returns number of bytes which write will write.

fn read(input: &mut dyn Read) -> Result<Self>

where Self: Sized,

Read Self from the input.

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.
