ProofStruct

cow_rs::composable::types

Struct ProofStruct 

Source 
pub struct ProofStruct {
    pub location: ProofLocation,
    pub data: Vec<u8>,
}
Expand description

On-chain Proof argument passed to ComposableCow::setRoot.

Bundles the proof location discriminant with location-specific data (e.g. an IPFS CID, Swarm hash, or Waku message). Pass data: vec![] for ProofLocation::Private or ProofLocation::Emitted.

Fields§

§location: ProofLocation

Where the Merkle proof is stored/communicated.

§data: Vec<u8>

Location-specific proof bytes (empty for private or emitted proofs).

Implementations§

Source§

impl ProofStruct

Source

pub const fn new(location: ProofLocation, data: Vec<u8>) -> Self

Construct a ProofStruct with the given location and data bytes.

§Arguments
  • location - Where the Merkle proof is stored or communicated.
  • data - Location-specific proof bytes (empty for private or emitted proofs).
§Returns

A new ProofStruct instance.

Source

pub const fn private() -> Self

A private proof (no location data needed).

§Returns

A ProofStruct with ProofLocation::Private and empty data.

Source

pub const fn emitted() -> Self

An emitted proof (no location data needed — the proof is in the tx log).

§Returns

A ProofStruct with ProofLocation::Emitted and empty data.

Source

pub const fn with_location(self, location: ProofLocation) -> Self

Override the proof location.

§Returns

The modified ProofStruct with the updated location (builder pattern).

Source

pub fn with_data(self, data: Vec<u8>) -> Self

Override the location-specific proof data bytes.

§Returns

The modified ProofStruct with the updated data (builder pattern).

Source

pub const fn is_private(&self) -> bool

Returns true if the proof location is ProofLocation::Private.

§Returns

true if location is ProofLocation::Private, false otherwise.

Source

pub const fn is_emitted(&self) -> bool

Returns true if the proof location is ProofLocation::Emitted.

§Returns

true if location is ProofLocation::Emitted, false otherwise.

Source

pub const fn is_swarm(&self) -> bool

Returns true if the proof location is ProofLocation::Swarm.

§Returns

true if location is ProofLocation::Swarm, false otherwise.

Source

pub const fn is_waku(&self) -> bool

Returns true if the proof location is ProofLocation::Waku.

§Returns

true if location is ProofLocation::Waku, false otherwise.

Source

pub const fn is_ipfs(&self) -> bool

Returns true if the proof location is ProofLocation::Ipfs.

§Returns

true if location is ProofLocation::Ipfs, false otherwise.

Source

pub const fn is_reserved(&self) -> bool

Returns true if the proof location is ProofLocation::Reserved.

§Returns

true if location is ProofLocation::Reserved, false otherwise.

Source

pub const fn has_data(&self) -> bool

Returns true if this proof has non-empty data bytes.

ProofLocation::Private and ProofLocation::Emitted proofs carry no data; IPFS, Swarm, and Waku proofs carry location-specific bytes.

Source

pub const fn is_empty(&self) -> bool

Returns true if this proof has no data bytes (complement of has_data).

Source

pub const fn data_len(&self) -> usize

Returns the number of data bytes in this proof.
