Struct fvm::kernel::BlockRegistry
source · pub struct BlockRegistry { /* private fields */ }
Expand description
A registry of open blocks (per-kernel). Think “file descriptor” table. At the moment, there’s no way to close/remove a block from this table.
Implementations§
source§impl BlockRegistry
impl BlockRegistry
sourcepub fn put_reachable(&mut self, block: Block) -> Result<BlockId>
pub fn put_reachable(&mut self, block: Block) -> Result<BlockId>
Adds a new block to the registry, marking all children as reachable, returning a handle to refer to it. Use this when adding a block known to be reachable.
sourcepub fn put_check_reachable(&mut self, block: Block) -> Result<BlockId>
pub fn put_check_reachable(&mut self, block: Block) -> Result<BlockId>
Adds a new block to the registry, checking that all children are currently reachable, returning a handle to refer to it. Use this when creating a new block.
sourcepub fn mark_reachable(&mut self, k: &Cid)
pub fn mark_reachable(&mut self, k: &Cid)
Mark a cid as reachable. Call this when a new block is linked into the state.
sourcepub fn is_reachable(&self, k: &Cid) -> bool
pub fn is_reachable(&self, k: &Cid) -> bool
Check if a block is reachable. Call this before attempting to read the block from the datastore.
sourcepub fn get(&self, id: BlockId) -> Result<&Block>
pub fn get(&self, id: BlockId) -> Result<&Block>
Gets the block associated with a block handle.
sourcepub fn stat(&self, id: BlockId) -> Result<BlockStat>
pub fn stat(&self, id: BlockId) -> Result<BlockStat>
Returns the size & codec of the specified block.
pub fn is_full(&self) -> bool
