Enum Asset 

pub enum Asset {
    Native,
    Credit(CreditAsset),
}

Represent an asset, either the native asset (XLM) or an asset issued.

Variants

Native

The native asset (XLM).

Credit(CreditAsset)

A non-native asset, identified by asset code/issuer id.

Implementations

impl Asset

pub fn new_native() -> Asset

Create the native asset: Lumens.

pub fn new_credit<S>(code: S, issuer: PublicKey) -> Result<Asset>

where S: Into<String>,

Create the asset with code issued by issuer.

pub fn is_native(&self) -> bool

Returns true if the asset is a Native. Returns false otherwise.

pub fn as_credit(&self) -> Option<&CreditAsset>

If the asset is a Credit, returns its value. Returns None otherwise

pub fn as_credit_mut(&mut self) -> Option<&mut CreditAsset>

If the asset is a Credit, returns its mutable value. Returns None otherwise

pub fn is_credit(&self) -> bool

Returns true if the asset is a Credit. Returns false otherwise.

pub fn to_xdr(&self) -> Result<Asset>

Returns the asset xdr object.

pub fn from_xdr(x: &Asset) -> Result<Asset>

Creates an asset from the xdr object.

Trait Implementations

impl Clone for Asset

fn clone(&self) -> Asset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Asset

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

Formats the value using the given formatter.

impl From<Asset> for TrustLineAsset

fn from(asset: Asset) -> Self

Converts to this type from the input type.

impl PartialEq for Asset

fn eq(&self, other: &Asset) -> 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 ReadXdr for Asset

fn read_xdr<R: Read>(r: &mut Limited<R>) -> Result<Self>

Read the XDR and construct the type.

fn read_xdr_to_end<R>(r: &mut Limited<R>) -> Result<Self, Error>

where R: Read,

Read the XDR and construct the type, and consider it an error if the read does not completely consume the read implementation.

fn read_xdr_into<R>(&mut self, r: &mut Limited<R>) -> Result<(), Error>

where R: Read,

Read the XDR and construct the type.

fn read_xdr_into_to_end<R>(&mut self, r: &mut Limited<R>) -> Result<(), Error>

where R: Read,

Read the XDR into the existing value, and consider it an error if the read does not completely consume the read implementation.

fn read_xdr_iter<R>(r: &mut Limited<R>) -> ReadXdrIter<&mut R, Self>

where R: Read,

Create an iterator that reads the read implementation as a stream of values that are read into the implementing type.

fn from_xdr(bytes: impl AsRef<[u8]>, limits: Limits) -> Result<Self, Error>

Construct the type from the XDR bytes.

impl WriteXdr for Asset

fn write_xdr<W: Write>(&self, w: &mut Limited<W>) -> Result<()>

fn to_xdr(&self, limits: Limits) -> Result<Vec<u8>, Error>
