Module collections 

Fallible, OOM-handling collections.

Modules

oom_abort

Collections which abort on OOM.

Macros

vec

Same as the std::vec! macro but returns an error on allocation failure.

Structs

EntitySet

Like cranelift_entity::EntitySet but enforces fallible allocation for all methods that allocate.

HashMap

A wrapper type around [hashbrown::hash_map::HashMap] that only exposes fallible allocation.

HashSet

A wrapper type around [hashbrown::hash_set::HashSet] that only exposes fallible allocation.

IndexMap

A wrapper around [indexmap::IndexMap] that only provides fallible allocation.

PrimaryMap

Like cranelift_entity::PrimaryMap but enforces fallible allocation for all methods that allocate.

SecondaryMap

Like cranelift_entity::SecondaryMap but all allocation is fallible.

String

A newtype wrapper around std::string::String that only exposes fallible-allocation methods.

Vec

Like std::vec::Vec but all methods that allocate force handling allocation failure.

Traits

TryClone

A trait for values that can be cloned, but contain owned, heap-allocated values whose allocations may fail during cloning.

TryCollect

Extension trait for an Iterator to fallibly collect into a container.

TryExtend

Analogue of Extend except handles OOM conditions.

TryFromIterator

Analogue of FromIterator in the standard library, but used with TryCollect::try_collect instead.

TryNew

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

Functions

try_new

Helper function to invoke <T as TryNew>::try_new.
