Trait ciruela::index::GetIndex [−] [src]

pub trait GetIndex {
    type Data: AsRef<[u8]>;
    type Error: Display;
    type Future: Future<Item = Self::Data, Error = Self::Error> + 'static;
    fn read_index(&self, id: &ImageId) -> Self::Future;
}

A trait to fulfill index data when uploading

Associated Types

`type Data: AsRef<[u8]>`

An index data returned

It's usually Vec<u8> but may also be an Arc'd container or a memory-mapped region.

`type Error: Display`

Error returned by future

This is used to print error and to send message to remote system

`type Future: Future<Item = Self::Data, Error = Self::Error> + 'static`

Future returned by read_block

Required Methods

`fn read_index(&self, id: &ImageId) -> Self::Future`

Read block by hash

Implementors

impl GetIndex for InMemoryIndexes type Data = Arc<[u8]>; type Error = ReadError; type Future = FutureResult<Arc<[u8]>, ReadError>;
