Struct IndirectBlock 

#[repr(C)]
pub struct IndirectBlock {
    lbas: [Option<LogicalBlockAddress>; 512],
}

Represents an indirect block in the filesystem.

An indirect block is used to extend the number of data blocks that an inode can reference. Instead of storing data directly, it contains a list of logical block addresses (LBAs), each pointing to a separate data block on disk.

This structure allows files to grow beyond the direct block limit imposed by the inode structure.

Usage

Typically used as part of indirect, or double-indirectblock addressing schemes to support large file sizes.

Fields

lbas: [Option<LogicalBlockAddress>; 512]

Trait Implementations

impl Default for IndirectBlock

fn default() -> Self

Returns the “default value” for a type.

impl Deref for IndirectBlock

type Target = [Option<LogicalBlockAddress>; 512]

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for IndirectBlock

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl MetaData for IndirectBlock

fn load( ffs: &FastFileSystemInner, lba: LogicalBlockAddress, ) -> Result<BlockPointsTo<Self>, KernelError>

Loads a metadata structure from disk at the specified logical block address.
