ProfileTree

dig_identity::tree

Struct ProfileTree 

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

A mutable DIG profile as a sparse merkle tree of slots.

Implementations§

Source§

impl ProfileTree

Source

pub fn new() -> Self

Creates an empty profile tree (root = all zeros).

Source

pub fn set(&mut self, slot: SlotId, value: &Value) -> Result<()>

Sets slot to value, replacing any prior value at that slot.

Source

pub fn set_encoded(&mut self, slot: SlotId, encoded: Vec<u8>) -> Result<()>

Sets slot to a pre-encoded value blob (used when relaying bytes without re-decoding them).

Source

pub fn remove(&mut self, slot: SlotId) -> Result<()>

Removes slot, making it provably absent.

Source

pub fn get_encoded(&self, slot: SlotId) -> Result<Option<Vec<u8>>>

Returns the pre-encoded value bytes at slot, or None if the slot is absent.

Source

pub fn get(&self, slot: SlotId) -> Result<Option<Value>>

Returns the decoded value at slot, or None if the slot is absent.

Source

pub fn root(&self) -> [u8; 32]

The current 32-byte merkle root committing to every set slot.

This is the value dig-identity DEFINES; WU3 pairs it with the on-chain DataStore root.

Source

pub fn prove_membership(&self, slot: SlotId) -> Result<ProfileProof>

Builds a membership proof that slot currently holds its set value.

Errors if slot is absent — use ProfileTree::prove_non_membership for that case so the intent (present vs absent) is explicit at the call site.

Source

pub fn prove_non_membership(&self, slot: SlotId) -> Result<ProfileProof>

Builds a non-membership proof that slot is currently absent.

Errors if slot is present, to prevent minting a “non-membership” proof for a set slot.
