Module pallet 

The pallet module in each FRAME pallet hosts the most important items needed to construct this pallet.

The main components of this pallet are:

• Pallet, which implements all of the dispatchable extrinsics of the pallet, among other public functions.
  • The subset of the functions that are dispatchable can be identified either in the dispatchables module or in the Call enum.
• storage_types, which contains the list of all types that are representing a storage item. Otherwise, all storage items are listed among Type Definitions.
• Config, which contains the configuration trait of this pallet.
• Event and Error, which are listed among the Enums.

Modules

dispatchables

Auto-generated docs-only module listing all defined dispatchables for this pallet.

storage_types

Auto-generated docs-only module listing all (public and private) defined storage types for this pallet.

Structs

EnsureAssetOwner

Config::CreateOrigin admitting a signed origin only when it owns the internal asset. Prevents creating a PSM over an asset you don’t control (PSM mint/burn bypasses the asset’s issuer checks).

ExternalAssetInfo

On-chain record of an external asset approved on a PSM instance.

Pallet

The Pallet struct, the main type that implements traits and standalone functions within the pallet.

PsmAdminInfo

Admin origins and creation-deposit bookkeeping for a PSM instance. Always written and removed together with the Psm entry.

PsmInfo

On-chain record of a PSM instance.

Enums

Call

Contains a variant per dispatchable extrinsic that this pallet has.

CircuitBreakerLevel

Circuit breaker levels for emergency control.

Error

The Error enum of this pallet.

Event

The Event enum of this pallet

HoldReason

A reason for this pallet placing a hold on funds.

PsmManagerLevel

Privilege level of an origin acting on a PSM instance.

Constants

MAX_DECIMALS_DIFF

Maximum absolute difference between an external asset’s decimals and the internal asset’s decimals. Bounds the scaling factor 10^diff well below u128::MAX so realistic balances cannot overflow during conversion.

Traits

Config

Configuration trait of this pallet.

Type Aliases

ModuleDeprecated

Type alias to Pallet, to be used by construct_runtime.

Psm

Registered PSM instances, keyed by the internal asset id.

PsmAdmin

Admin origins and creation-deposit bookkeeping per PSM, keyed by the internal asset id. Held separately from Psm so swaps never decode the admin origins. Always written and removed together with the corresponding Psm entry.

PsmDebt

Internal-asset debt minted through PSM, per (internal, external) pair.
