Enum odra_modules::cep78::modalities::MetadataMutability

#[repr(u8)]
pub enum MetadataMutability {
    Immutable = 0,
    Mutable = 1,
}

The metadata mutability mode governs the behavior around updates to a given NFTs metadata.

The Mutable option cannot be used in conjunction with the Hash modality for the NFT identifier; attempting to install the contract with this configuration raises super::error::CEP78Error::InvalidMetadataMutability error.

This modality is a required installation parameter and cannot be changed once the contract has been installed.

Variants

Immutable = 0

Metadata for NFTs minted in this mode cannot be updated once the NFT has been minted.

Mutable = 1

Metadata for NFTs minted in this mode can update the metadata via the set_token_metadata entrypoint.

Trait Implementations

impl CLTyped for MetadataMutability

fn cl_type() -> CLType

The CLType of Self.

impl Clone for MetadataMutability

fn clone(&self) -> MetadataMutability

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataMutability

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

Formats the value using the given formatter.

impl Default for MetadataMutability

fn default() -> MetadataMutability

Returns the “default value” for a type.

impl FromBytes for MetadataMutability

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 HasEvents for MetadataMutability

fn events() -> Vec<Event>

Returns a list of Events used by the contract.

fn event_schemas() -> BTreeMap<String, Schema>

Returns a map of event schemas used by the contract.

impl NamedCLTyped for MetadataMutability

fn ty() -> NamedCLType

Returns the NamedCLType of the implementing type.

impl Ord for MetadataMutability

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for MetadataMutability

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for MetadataMutability

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl SchemaCustomTypes for MetadataMutability

fn schema_types() -> Vec<Option<CustomType>>

Returns a vector of optional CustomTypes.

impl ToBytes for MetadataMutability

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>.

fn write_bytes(&self, writer: &mut Vec<u8>) -> Result<(), Error>

Writes &self into a mutable writer.

impl TryFrom<u8> for MetadataMutability

type Error = CEP78Error

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for MetadataMutability

impl Eq for MetadataMutability

impl SchemaCustomElement for MetadataMutability

impl StructuralPartialEq for MetadataMutability
