Implementations

impl PlutusMap

pub fn new() -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn set(&mut self, key: PlutusData, value: PlutusData)

Replaces all datums of a given key, if any exist.

pub fn get(&self, key: &PlutusData) -> Option<&PlutusData>

Gets the plutus datum corresponding to a given key, if it exists. Note: In the case of duplicate keys this only returns the first datum. This is an extremely rare occurence on-chain but can happen.

pub fn get_all(&self, key: &PlutusData) -> Option<Vec<&PlutusData>>

In the extremely unlikely situation there are duplicate keys, this gets all of a single key

Trait Implementations

impl Clone for PlutusMap

fn clone(&self) -> PlutusMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PlutusMap

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

Formats the value using the given formatter.

impl Default for PlutusMap

fn default() -> PlutusMap

Returns the “default value” for a type.

impl Deserialize for PlutusMap

fn deserialize<R: BufRead + Seek>( raw: &mut Deserializer<R>, ) -> Result<Self, DeserializeError>

fn from_cbor_bytes(data: &[u8]) -> Result<Self, DeserializeError>

where Self: Sized,

from-bytes using the exact CBOR format specified in the CDDL binary spec. For hashes/addresses/etc this will include the CBOR bytes type/len/etc.

impl Hash for PlutusMap

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 Ord for PlutusMap

fn cmp(&self, other: &Self) -> 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,

Restrict a value to a certain interval.

impl PartialEq for PlutusMap

fn eq(&self, other: &Self) -> 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 PlutusMap

fn partial_cmp(&self, other: &Self) -> 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 Serialize for PlutusMap

fn serialize<'se, W: Write>( &self, serializer: &'se mut Serializer<W>, force_canonical: bool, ) -> Result<&'se mut Serializer<W>>

fn to_cbor_bytes(&self) -> Vec<u8>

Bytes of a structure using the CBOR bytes as per the CDDL spec which for foo = bytes will include the CBOR bytes type/len, etc. This gives the original bytes in the case where this was created from bytes originally, or will use whatever the specific encoding details are present in any encoding details struct for the type.

fn to_canonical_cbor_bytes(&self) -> Vec<u8>

Bytes of a structure using the CBOR bytes as per the CDDL spec which for foo = bytes will include the CBOR bytes type/len, etc. This gives the canonically encoded CBOR bytes always
