Struct Block 

pub struct Block<B = Bytes> {
    pub offset: u64,
    pub data: B,
}

Re-export core types. Data block at a specific offset

The buffer type B is generic and can be any type that implements AsRef<[u8]> + Send, allowing for:

• bytes::Bytes — zero-copy slices
• Vec<u8> — owned buffers
• Box<[u8]> — boxed slices
• DMA buffers
• Custom zero-copy types

The default buffer type is bytes::Bytes, which provides zero-copy slices for I/O operations.

Fields

offset: u64

Absolute byte offset where the block starts

data: B

Buffer containing the block data

Implementations

impl<B: AsRef<[u8]>> Block<B>

pub const fn new(offset: u64, data: B) -> Self

Create a new block at the given offset with the given data

pub fn range(&self) -> Range

Returns the range covered by this block

pub fn len(&self) -> usize

Returns the length of the block data

pub fn is_empty(&self) -> bool

Returns true if the block has no data

Trait Implementations

impl<B: AsRef<[u8]>> AsRef<[u8]> for Block<B>

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl<B: AsRef<[u8]> + Clone> Clone for Block<B>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<B: AsRef<[u8]> + Debug> Debug for Block<B>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
