Metadata for a coin type

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

id: Option<ObjectId>

ObjectId of the 0x2::coin::CoinMetadata object or 0x2::iota::coin_registry::Currency object (when registered with CoinRegistry).

decimals: Option<u32>

Number of decimal places the coin uses.

name: Option<String>

Name for the token

symbol: Option<String>

Symbol for the token

description: Option<String>

Description of the token

icon_url: Option<String>

URL for the token logo

metadata_cap_id: Option<ObjectId>

The MetadataCap ID if it has been claimed for this coin type. This capability allows updating the coin’s metadata fields. Only populated when metadata is from CoinRegistry.

metadata_cap_state: Option<i32>

State of the MetadataCap for this coin type.

impl PartialEq for CoinMetadata

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