The non-fungible assets.
Implementations§
§impl AssetsInHolding
impl AssetsInHolding
pub fn new() -> AssetsInHolding
pub fn new() -> AssetsInHolding
New value, containing no assets.
pub fn fungible_assets_iter(&self) -> impl Iterator<Item = Asset>
pub fn fungible_assets_iter(&self) -> impl Iterator<Item = Asset>
A borrowing iterator over the fungible assets.
pub fn non_fungible_assets_iter(&self) -> impl Iterator<Item = Asset>
pub fn non_fungible_assets_iter(&self) -> impl Iterator<Item = Asset>
A borrowing iterator over the non-fungible assets.
pub fn into_assets_iter(self) -> impl Iterator<Item = Asset>
pub fn into_assets_iter(self) -> impl Iterator<Item = Asset>
A consuming iterator over all assets.
pub fn assets_iter(&self) -> impl Iterator<Item = Asset>
pub fn assets_iter(&self) -> impl Iterator<Item = Asset>
A borrowing iterator over all assets.
pub fn subsume_assets(&mut self, assets: AssetsInHolding)
pub fn subsume_assets(&mut self, assets: AssetsInHolding)
Mutate self
to contain all given assets
, saturating if necessary.
NOTE: AssetsInHolding
are always sorted, allowing us to optimize this function from
O(n^2)
to O(n)
.
pub fn subsume(&mut self, asset: Asset)
pub fn subsume(&mut self, asset: Asset)
Mutate self
to contain the given asset
, saturating if necessary.
Wildcard values of asset
do nothing.
pub fn swapped(&mut self, with: AssetsInHolding) -> AssetsInHolding
pub fn swapped(&mut self, with: AssetsInHolding) -> AssetsInHolding
Swaps two mutable AssetsInHolding, without deinitializing either one.
pub fn prepend_location(&mut self, prepend: &Location)
pub fn prepend_location(&mut self, prepend: &Location)
Alter any concretely identified assets by prepending the given Location
.
WARNING: For now we consider this infallible and swallow any errors. It is thus the caller’s responsibility to ensure that any internal asset IDs are able to be prepended without overflow.
pub fn reanchor(
&mut self,
target: &Location,
context: &Junctions,
maybe_failed_bin: Option<&mut AssetsInHolding>,
)
pub fn reanchor( &mut self, target: &Location, context: &Junctions, maybe_failed_bin: Option<&mut AssetsInHolding>, )
Mutate the assets to be interpreted as the same assets from the perspective of a target
chain. The local chain’s context
is provided.
Any assets which were unable to be reanchored are introduced into failed_bin
.
pub fn contains_asset(&self, asset: &Asset) -> bool
pub fn contains_asset(&self, asset: &Asset) -> bool
Returns true
if asset
is contained within self
.
pub fn contains_assets(&self, assets: &Assets) -> bool
pub fn contains_assets(&self, assets: &Assets) -> bool
Returns true
if all assets
are contained within self
.
pub fn contains(&self, assets: &AssetsInHolding) -> bool
pub fn contains(&self, assets: &AssetsInHolding) -> bool
Returns true
if all assets
are contained within self
.
pub fn ensure_contains(&self, assets: &Assets) -> Result<(), TakeError>
pub fn ensure_contains(&self, assets: &Assets) -> Result<(), TakeError>
Returns an error unless all assets
are contained in self
. In the case of an error, the
first asset in assets
which is not wholly in self
is returned.
pub fn saturating_take(&mut self, asset: AssetFilter) -> AssetsInHolding
pub fn saturating_take(&mut self, asset: AssetFilter) -> AssetsInHolding
Mutates self
to its original value less mask
and returns true
iff it contains at least
mask
.
Returns Ok
with the non-wildcard equivalence of mask
taken and mutates self
to its
value minus mask
if self
contains asset
, and return Err
otherwise.
pub fn try_take(
&mut self,
mask: AssetFilter,
) -> Result<AssetsInHolding, TakeError>
pub fn try_take( &mut self, mask: AssetFilter, ) -> Result<AssetsInHolding, TakeError>
Mutates self
to its original value less mask
and returns true
iff it contains at least
mask
.
Returns Ok
with the non-wildcard equivalence of asset
taken and mutates self
to its
value minus asset
if self
contains asset
, and return Err
otherwise.
pub fn checked_sub(
self,
asset: Asset,
) -> Result<AssetsInHolding, AssetsInHolding>
pub fn checked_sub( self, asset: Asset, ) -> Result<AssetsInHolding, AssetsInHolding>
Consumes self
and returns its original value excluding asset
iff it contains at least
asset
.
pub fn min(&self, mask: &AssetFilter) -> AssetsInHolding
pub fn min(&self, mask: &AssetFilter) -> AssetsInHolding
Return the assets in self
, but (asset-wise) of no greater value than mask
.
The number of unique assets which are returned will respect the count
parameter in the
counted wildcard variants of mask
.
Example:
use staging_xcm_executor::AssetsInHolding;
use xcm::latest::prelude::*;
let assets_i_have: AssetsInHolding = vec![ (Here, 100).into(), (Junctions::from([GeneralIndex(0)]), 100).into() ].into();
let assets_they_want: AssetFilter = vec![ (Here, 200).into(), (Junctions::from([GeneralIndex(0)]), 50).into() ].into();
let assets_we_can_trade: AssetsInHolding = assets_i_have.min(&assets_they_want);
assert_eq!(assets_we_can_trade.into_assets_iter().collect::<Vec<_>>(), vec![
(Here, 100).into(), (Junctions::from([GeneralIndex(0)]), 50).into(),
]);
