Implementations§

source§

impl<T, const H: usize, const A: usize> Opening<T, H, A>
where T: Aggregate<A> + Clone,

source

pub fn root(&self) -> &T

Returns the root of the opening.

source

pub fn branch(&self) -> &[[T; A]; H]

Returns the branch of the opening.

source

pub fn positions(&self) -> &[usize; H]

Returns the indices for the path in the opening.

source

pub fn verify(&self, item: impl Into<T>) -> bool
where T: PartialEq,

source

pub fn to_var_bytes<const T_SIZE: usize>(&self) -> Vec<u8>
where T: Serializable<T_SIZE>,

Serialize an Opening to a vector of bytes.

source

pub fn from_slice<const T_SIZE: usize>(buf: &[u8]) -> Result<Self, BytesError>
