[Seri]

apply() has the inline property, which allows it to copy the suspending context of its caller

[Seri]

i.e. if you’re already calling it from a suspending block of code, you’re good

[Seri]

inline fun T.apply(block: T.() -> Unit): T

[Animesh Sahu]

@Seri It does not work, in my case if you can correct some kindof code:

kotlin
private suspend fun createUserSession(session: WebSocketServerSession, block: suspend UserSessionBuilder.() -> Unit): UserSession {
		return UserSessionBuilder(session, server).apply(block).create()
	}

here apply(block) give compiler error that type interference failed

[Animesh Sahu]

Type inference failed:
required: UserSessionBuilder.()->Unit
found: suspend UserSessionBuilder.()->Unit

Suspend lambdas are not compatible with regular lambdas. You cannot pass it directly as a parameter of apply, but should instead write :

return UserSessionBuilder(session, server).apply { block() }.create()

Exactly, thanks @tseisel

Ah, thanks
