Struct casper_types::contracts::Group

pub struct Group(_);

A (labelled) "user group". Each method of a versioned contract may be assoicated with one or more user groups which are allowed to call it.

Implementations

impl Group

pub fn new<T: Into<String>>(s: T) -> Self

Basic constructor

pub fn value(&self) -> &str

Retrieves underlying name.

Trait Implementations

impl Clone for Group

fn clone(&self) -> Group

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Group

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

Formats the value using the given formatter.

impl Eq for Group

impl From<Group> for String

fn from(group: Group) -> Self

Performs the conversion.

impl FromBytes for Group

fn from_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), Error>

Deserializes the slice into Self.

fn from_vec(bytes: Vec<u8>) -> Result<(Self, Vec<u8>), Error>

Deserializes the Vec<u8> into Self.

impl Ord for Group

fn cmp(&self, other: &Group) -> Ordering

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Group> for Group

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

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

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

This method tests for !=.

impl PartialOrd<Group> for Group

fn partial_cmp(&self, other: &Group) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Group) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Group) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Group) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Group) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StructuralEq for Group

impl StructuralPartialEq for Group

impl ToBytes for Group

fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serializes &self to a Vec<u8>.

fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> which would be returned from a successful call to to_bytes() or into_bytes(). The data is not actually serialized, so this call is relatively cheap.

fn into_bytes(self) -> Result<Vec<u8>, Error> where
    Self: Sized, 

Consumes self and serializes to a Vec<u8>.
