Global

rama::crypto::dep::x509_parser::prelude::asn1_rs::nom::lib::std::alloc

Struct Global 

Source 
pub struct Global;
🔬This is a nightly-only experimental API. (allocator_api)
Available on crate features crypto and std only.
Expand description

The global memory allocator.

This type implements the Allocator trait by forwarding calls to the allocator registered with the #[global_allocator] attribute if there is one, or the std crate’s default.

Note: while this type is unstable, the functionality it provides can be accessed through the free functions in alloc.
