Std.Http.Server.Lambda.nextInvocation

fn

This is a callable function.

What it does

Ask for the next invocation, waiting until there is one.

The identifier comes back in a header rather than in the body, so a reader

that only decoded the body would answer every invocation against nothing.

Read the signature

• The text after the name is the type checked by Pudu.
• Read arrows from left to right: inputs come first, and the final type is returned.
• & borrows a value for this call instead of moving or copying it.
• Names inside [ ] are type arguments, such as the item type held by a collection.
• Result makes success and recoverable failure part of the function's type.
