Trait LayoutReaderFactory 

pub trait LayoutReaderFactory:
    'static
    + Send
    + Sync {
    // Required method
    fn open<'life0, 'async_trait>(
        &'life0 self,
    ) -> Pin<Box<dyn Future<Output = VortexResult<Option<LayoutReaderRef>>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

An async factory that produces a LayoutReaderRef.

Implementations handle file opening, footer caching, and statistics-based pruning. Returns None if the source should be skipped (e.g., pruned based on file-level statistics before the reader is fully constructed).

Required Methods

fn open<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = VortexResult<Option<LayoutReaderRef>>> + Send + 'async_trait>>

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

Opens the layout reader, or returns None if it should be skipped.

Dyn Compatibility

This trait is dyn compatible.

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