Trait AsyncReader 

pub trait AsyncReader<'a> {
    type Reader: RangeReader;

    // Required methods
    fn metadata<'async_trait>(
        &'a mut self,
    ) -> Pin<Box<dyn Future<Output = Result<FileMetadata>> + Send + 'async_trait>>
       where Self: 'async_trait,

        &'a mut self,
        blob_metadata: &BlobMetadata,
    ) -> Result<Self::Reader>;
}

AsyncReader defines an asynchronous reader for puffin data.

Required Associated Types

type Reader: RangeReader

Required Methods

fn metadata<'async_trait>( &'a mut self, ) -> Pin<Box<dyn Future<Output = Result<FileMetadata>> + Send + 'async_trait>>

where Self: 'async_trait, 'a: 'async_trait,

Fetches the FileMetadata.

fn blob_reader( &'a mut self, blob_metadata: &BlobMetadata, ) -> Result<Self::Reader>

Reads particular blob data based on given metadata.

Data read from the reader is compressed leaving the caller to decompress the data.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl<'a, R: RangeReader + 'a> AsyncReader<'a> for PuffinFileReader<R>

type Reader = PartialReader<&'a R>
