Struct Metadata

pub struct Metadata {
    pub description: String,
    pub denom_units: Vec<DenomUnit>,
    pub base: String,
    pub display: String,

Metadata represents a struct that describes a basic token.

Fields

description: String

denom_units: Vec<DenomUnit>

denom_units represents the list of DenomUnit’s for a given coin

base: String

base represents the base denom (should be the DenomUnit with exponent = 0).

display: String

display indicates the suggested denom that should be displayed in clients.

name: String

name defines the name of the token (eg: Cosmos Atom)

Since: cosmos-sdk 0.43

symbol: String

symbol is the token symbol usually shown on exchanges (eg: ATOM). This can be the same as the display.

Since: cosmos-sdk 0.43

uri: String

URI to a document (on or off-chain) that contains additional information. Optional.

Since: cosmos-sdk 0.46

uri_hash: String

URIHash is a sha256 hash of a document pointed by URI. It’s used to verify that the document didn’t change. Optional.

Since: cosmos-sdk 0.46

Trait Implementations

impl Clone for Metadata

fn clone(&self) -> Metadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Metadata

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

Formats the value using the given formatter.

impl Default for Metadata

fn default() -> Self

Returns the “default value” for a type.

impl Message for Metadata

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

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

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

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

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Metadata

fn eq(&self, other: &Metadata) -> 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.
