Trait TryNew 

pub trait TryNew {
    type Value;

    // Required method
    fn try_new(value: Self::Value) -> Result<Self, OutOfMemory>
       where Self: Sized;
}

Extension trait providing fallible allocation for types like Arc<T> and Box<T>.

Required Associated Types

type Value

The inner T type that is getting wrapped into an Arc<T> or Box<T>.

Required Methods

fn try_new(value: Self::Value) -> Result<Self, OutOfMemory>

where Self: Sized,

Allocate a new Self, returning Err(OutOfMemory) on allocation failure.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl<T> TryNew for Arc<T>

XXX: Stable Rust doesn’t actually give us any method to build fallible allocation for Arc<T>, so this is only actually fallible when using nightly Rust and setting RUSTFLAGS="--cfg arc_try_new".

type Value = T

fn try_new(value: T) -> Result<Self, OutOfMemory>

where Self: Sized,

impl<T> TryNew for Box<T>

type Value = T

fn try_new(value: T) -> Result<Self, OutOfMemory>

where Self: Sized,
