Struct arbitrary::FiniteBuffer

pub struct FiniteBuffer<'a> { /* fields omitted */ }

A source of unstructured data with a finite size

This buffer is a finite source of unstructured data. Once the data is exhausted it stays exhausted.

Methods

impl<'a> FiniteBuffer<'a>

pub fn new(buffer: &'a [u8], max_len: usize) -> Result<Self, BufferError>

Create a new FiniteBuffer

If the passed buffer is shorter than max_len the total number of bytes will be the bytes available in buffer. If buffer is longer than max_len the buffer will be trimmed.

Trait Implementations

impl<'a> Unstructured for FiniteBuffer<'a>

type Error = ()

The error type for Unstructured, see implementations for details

fn fill_buffer(&mut self, buffer: &mut [u8]) -> Result<(), Self::Error>

Fill a buffer with bytes, forming the unstructured data from which Arbitrary structured data shall be generated.

fn container_size(&mut self) -> Result<usize, Self::Error>

Generate a size for container.
