Struct PinManager 

pub struct PinManager { /* private fields */ }

Pin manager for tracking pinned blocks

Implementations

impl PinManager

pub fn new() -> Self

Create a new pin manager

pub fn pin(&self, cid: &Cid) -> Result<()>

Pin a block directly (single block only)

pub fn pin_named(&self, cid: &Cid, name: String) -> Result<()>

Pin a block with a name

pub fn pin_recursive<F>(&self, cid: &Cid, link_resolver: F) -> Result<usize>

where F: Fn(&Cid) -> Result<Vec<Cid>>,

Pin a block recursively (pins all referenced blocks)

The link_resolver function should return all CIDs that this block links to.

pub fn unpin(&self, cid: &Cid) -> Result<bool>

Unpin a block

pub fn unpin_recursive<F>(&self, cid: &Cid, link_resolver: F) -> Result<usize>

where F: Fn(&Cid) -> Result<Vec<Cid>>,

Unpin a block recursively

pub fn is_pinned(&self, cid: &Cid) -> bool

Check if a block is pinned

pub fn get_pin_info(&self, cid: &Cid) -> Option<PinInfo>

Get pin info for a block

pub fn list_pins(&self) -> Result<Vec<(Cid, PinInfo)>>

List all pinned CIDs

pub fn list_pins_by_type(&self, pin_type: PinType) -> Result<Vec<Cid>>

List pins of a specific type

pub fn stats(&self) -> PinStatsSnapshot

Get statistics

pub fn save_to_file(&self, path: &Path) -> Result<()>

Save pins to a file

pub fn load_from_file(path: &Path) -> Result<Self>

Load pins from a file

pub fn clear(&self)

Clear all pins

Trait Implementations

impl Default for PinManager

fn default() -> Self

Returns the “default value” for a type.
