Struct libflate::finish::AutoFinish

pub struct AutoFinish<T: Complete> { /* fields omitted */ }

A wrapper struct that completes the processing of the underlying instance when drops.

This calls Complete:::complete method of T when drops.

Panics

If the invocation of Complete::complete(T) returns an error, AutoFinish::drop() will panic.

Methods

impl<T: Complete> AutoFinish<T>

pub fn new(inner: T) -> Self

Makes a new AutoFinish instance.

Examples

use std::io;
use libflate::finish::AutoFinish;
use libflate::gzip::Encoder;

let plain = b"Hello World!";
let mut buf = Vec::new();
let mut encoder = AutoFinish::new(Encoder::new(&mut buf).unwrap());
io::copy(&mut &plain[..], &mut encoder).unwrap();

pub fn into_inner(self) -> T

Unwraps this AutoFinish instance, returning the underlying instance.

Trait Implementations
