Expand description

Dispatch system. Contains a macro for defining runtime modules and generating values representing lazy module function calls.

Modules

Utilities for formatting and printing Strings.

Primitive traits and types representing basic properties of types.

Error handling with the Result type.

Macros

Derive macro generating an impl of the trait Clone.

Derive macro generating an impl of the trait Eq.

Derive macro generating an impl of the trait PartialEq.

Structs

The function and pallet name of the Call.

A contiguous growable array type, written as Vec<T> and pronounced ‘vector’.

Enums

Reason why a dispatch call failed.

Traits

Serializable version of pallet dispatchable.

A common trait for the ability to explicitly duplicate an object.

Trait that allows zero-copy read/write of value-references to/from slices in LE format.

Trait that allows zero-copy read of value-references from slices in LE format.

A lazy call (module function and argument values) that can be executed via its dispatch method.

Trait that allows zero-copy write of value-references to slices in LE format.

Something that can be encoded as a reference.

A marker trait that tells the compiler that a type encode to the same representation as another type.

Trait for equality comparisons which are equivalence relations.

Gets the metadata for the Call - function name and pallet name.

Gets the function name of the Call.

Provides information about the storage version of a pallet.

Trait that tells you if a given type can be encoded/decoded in a compact way.

Trait that allows reading of data into a slice.

Trait that allows writing of data.

A type that can be used as a parameter in a dispatchable function.

Trait for equality comparisons which are partial equivalence relations.

Type that can be dispatched with an origin but without checking the origin filter.

Type Definitions

The error type contained in a DispatchResultWithPostInfo.

Unaugmented version of DispatchResultWithPostInfo that can be returned from dispatchable functions and is automatically converted to the augmented type. Should be used whenever the PostDispatchInfo does not need to be overwritten. As this should be the common case it is the implicit return type when none is specified.

The return type of a Dispatchable in frame. When returned explicitly from a dispatchable function it allows overriding the default PostDispatchInfo returned from a dispatch.

Priority for a transaction. Additive. Higher is better.

Derive Macros

Derive parity_scale_codec::Decode and for struct and enum.

Derive parity_scale_codec::Encode and parity_scale_codec::EncodeLike for struct and enum.
