Struct NotTaskSafe 

pub struct NotTaskSafe {
    pub path: String,
    pub type_name: String,
}

The first value in a capture that may not cross a task boundary.

Fields

path: String

How the offending value is reached from the closure, such as app.metrics or handler -> builder.

type_name: String

The type that is not task-safe.

Implementations

impl NotTaskSafe

pub fn subject(&self) -> String

How the offending value is named in a diagnostic: as the type itself when the value under test is the problem, and with the path to it when the problem is nested inside a larger value.

A path is written as it is reached from the value under test, so a leading . is dropped: the root has no name to hang it on.

pub fn help(&self, boundary: &str) -> String

The correction the Language Card promises for this violation, at the boundary that rejected the value: spawn for a task, Shared for a synchronized handle.
