// Package geth contains the simplified mobile APIs to go-ethereum.
|
||||
//
|
||||
// The scope of this package is *not* to allow writing a custom Ethereum client
|
||||
// with pieces plucked from go-ethereum, rather to allow writing native dapps on
|
||||
// mobile platforms. Keep this in mind when using or extending this package!
|
||||
//
|
||||
// API limitations
|
||||
//
|
||||
// Since gomobile cannot bridge arbitrary types between Go and Android/iOS, the
|
||||
// exposed APIs need to be manually wrapped into simplified types, with custom
|
||||
// constructors and getters/setters to ensure that they can be meaninfully used
|
||||
// from Java/ObjC too.
|
||||
//
|
||||
// With this in mind, please try to limit the scope of this package and only add
|
||||
// essentials without which mobile support cannot work, especially since manually
|
||||
// syncing the code will be unwieldy otherwise. In the long term we might consider
|
||||
// writing custom library generators, but those are out of scope now.
|
||||
//
|
||||
// Content wise each file in this package corresponds to an entire Go package
|
||||
// from the go-ethereum repository. Please adhere to this scoping to prevent this
|
||||
// package getting unmaintainable.
|
||||
//
|
||||
// Wrapping guidelines:
|
||||
//
|
||||
// Every type that is to be exposed should be wrapped into its own plain struct,
|
||||
// which internally contains a single field: the original go-ethereum version.
|
||||
// This is needed because gomobile cannot expose named types for now.
|
||||
//
|
||||
// Whenever a method argument or a return type is a custom struct, the pointer
|
||||
// variant should always be used as value types crossing over between language
|
||||
// boundaries might have strange behaviors.
|
||||
//
|
||||
// Slices of types should be converted into a single multiplicative type wrapping
|
||||
// a go slice with the methods `Size`, `Get` and `Set`. Further slice operations
|
||||
// should not be provided to limit the remote code complexity. Arrays should be
|
||||
// avoided as much as possible since they complicate bounds checking.
|
||||
//
|
||||
// If a method has multiple return values (e.g. some return + an error), those
|
||||
// are generated as output arguments in ObjC. To avoid weird generated names like
|
||||
// ret_0 for them, please always assign names to output variables if tuples.
|
||||
//
|
||||
// Note, a panic *cannot* cross over language boundaries, instead will result in
|
||||
// an undebuggable SEGFAULT in the process. For error handling only ever use error
|
||||
// returns, which may be the only or the second return.
