Trait BlobGuard 

pub trait BlobGuard {
    type Reader: RangeReader;

    // Required method
    fn reader<'life0, 'async_trait>(
        &'life0 self,
    ) -> Pin<Box<dyn Future<Output = Result<Self::Reader>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

BlobGuard is provided by the PuffinReader to access the blob data. Users should hold the BlobGuard until they are done with the blob data.

Required Associated Types

type Reader: RangeReader

Required Methods

fn reader<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Self::Reader>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Dyn Compatibility

This trait is dyn compatible.

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