BlockLease

Struct BlockLease 

Source
pub struct BlockLease { /* private fields */ }
Expand description

A block storage lease that auto-frees on drop.

Wraps a FabricBlock handle with RAII lifecycle management. When the BlockLease is dropped, the underlying resource will be released (once the host provides an explicit fbbu_free() call).

Created via BlockBuilder::acquire.

§Examples

use grafos_std::block::{BlockBuilder, BLOCK_SIZE};

let lease = BlockBuilder::new().min_blocks(16).acquire()?;
let data = [42u8; BLOCK_SIZE];
lease.block().write_block(0, &data)?;
// lease is freed when it goes out of scope

Implementations§

Source§

impl BlockLease

Source

pub fn block(&self) -> &FabricBlock

pub fn info(&self) -> LeaseInfo

Lease metadata snapshot (id, creation time, expiry, and status).

Source

pub fn lease_id(&self) -> u128

Source

pub fn created_at_unix_secs(&self) -> u64

Source

pub fn renew(&self, duration_secs: u64) -> Result<()>
