Struct protobuf::rt::Lazy

source · [−]

pub struct Lazy<T> { /* private fields */ }

Expand description

Lazily initialized static variable.

Used in generated code.

Currently a wrapper around once_cells OnceCell.

source

impl<T> Lazy<T>

source

pub const fn new() -> Lazy<T>

Uninitialized state.

source

pub fn get(&self, f: impl FnOnce() -> T) -> &T

Lazily initialize the value.
