Trait solana_evm_loader_program::scope::evm::secp256k1::secp256k1_sys::CPtr[−][src]

[+] Show declaration

pub trait CPtr {
    type Target;
    pub fn as_c_ptr(&self) -> *const Self::Target;
    pub fn as_mut_c_ptr(&mut self) -> *mut Self::Target;
}

A trait for producing pointers that will always be valid in C. (assuming NULL pointer is a valid no-op) Rust doesn’t promise what pointers does it give to ZST (https://doc.rust-lang.org/nomicon/exotic-sizes.html#zero-sized-types-zsts) In case the type is empty this trait will give a NULL pointer, which should be handled in C.
