Trait Map

pub trait Map<T> {
    // Required method
    fn map<F>(self, f: F) -> Self
       where F: FnOnce(T) -> T;
}

Copied from syntax::ptr::P of rustc.

Required Methods

fn map<F>(self, f: F) -> Self

where F: FnOnce(T) -> T,

Transform the inner value, consuming self and producing a new P<T>.

Memory leak

This will leak self if the given closure panics.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
