Expand description

Lasily initialized data.

Implementations

source

impl<T> Lazy<T>

source

pub const INIT: Lazy<T> = _

Uninitialized Lazy object.

The initializer is added in rust-protobuf 2.11, for compatibility with previously generated code, existing fields are kept public.

source

pub fn get<F>(&'static mut self, init: F) -> &'static Twhere
F: FnOnce() -> T,

Get lazy field value, initialize it with given function if not yet.

Performs the conversion.

source

impl<T, U> TryInto for Twhere
U: TryFrom<T>,

type Error = >::Error

const: unstable · source

fn try_into(self) -> Result<U, >::Error>

Performs the conversion.
