Struct identity_iota::credential::status_list_2021::StatusList2021

pub struct StatusList2021(/* private fields */);

StatusList2021 data structure as described in W3C’s VC status list 2021.

Implementations

impl StatusList2021

pub fn new(num_entries: usize) -> Result<StatusList2021, StatusListError>

Returns a new zero-filled StatusList2021 that can hold num_entries credential statuses.

Notes:

• The actual length of the list will be rounded up to the closest multiple of 8 to accomodate for byte sizes.
• num_entries must be at least 131,072 which corresponds to a size of 16KB.

pub const fn len(&self) -> usize

Returns the number of entries.

pub fn get(&self, index: usize) -> Result<bool, StatusListError>

Returns the status of the index-th entry, if it exists.

pub fn set(&mut self, index: usize, value: bool) -> Result<(), StatusListError>

Sets the status of the index-th entry to value.

pub fn try_from_encoded_str(s: &str) -> Result<StatusList2021, StatusListError>

Attempts to parse a StatusList2021 from a string, following the StatusList2021 expansion algorithm.

pub fn into_encoded_str(self) -> String

Encode this StatusList2021 into its string representation following StatusList2021 generation algorithm.

Trait Implementations

impl Clone for StatusList2021

fn clone(&self) -> StatusList2021

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StatusList2021

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for StatusList2021

fn default() -> StatusList2021

Returns the “default value” for a type.

impl Hash for StatusList2021

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for StatusList2021

fn eq(&self, other: &StatusList2021) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
