Struct core::alloc::AllocError

source ·
pub struct AllocError;
🔬This is a nightly-only experimental API. (allocator_api #32838)
Expand description

The AllocError error indicates an allocation failure that may be due to resource exhaustion or to something wrong when combining the given input arguments with this allocator.

fn provide<'a>(&'a self, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access #99301)

impl PartialEq<AllocError> for AllocError

source§

fn eq(&self, other: &AllocError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
