Trait Implementations

impl BlockReader for FileReader

fn block_size(&self) -> u32

Logical block size in bytes.

fn total_blocks<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = GibbloxResult<u64>> + Send + 'async_trait>>

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

Total number of logical blocks available.

fn write_identity(&self, out: &mut dyn Write) -> Result

Write a stable, canonical identity string for this block reader.

fn read_blocks<'life0, 'life1, 'async_trait>( &'life0 self, lba: u64, buf: &'life1 mut [u8], ctx: ReadContext, ) -> Pin<Box<dyn Future<Output = GibbloxResult<usize>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Read one or more blocks starting at lba into buf.

impl ByteReader for FileReader

fn size_bytes<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = GibbloxResult<u64>> + Send + 'async_trait>>

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

Total source size in bytes.

fn write_identity(&self, out: &mut dyn Write) -> Result

Write a stable, canonical identity string for this byte reader.

fn read_at<'life0, 'life1, 'async_trait>( &'life0 self, offset: u64, buf: &'life1 mut [u8], _ctx: ReadContext, ) -> Pin<Box<dyn Future<Output = GibbloxResult<usize>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,
