Structs

Context	A Secp256k1 context, containing various precomputed values and such needed to do elliptic curve computations. If you create one of these with `secp256k1_context_create` you MUST destroy it with `secp256k1_context_destroy`, or else you will have a memory leak.

Constants

RANGEPROOF_MAX_LENGTH	Rangeproof maximum length
SECP256K1_SER_COMPRESSED	Flag for keys to indicate compressed serialization format
SECP256K1_SER_UNCOMPRESSED	Flag for keys to indicate uncompressed serialization format

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.

Type Definitions

EcdhHashFn	Hash function to use to post-process an ECDH point to get a shared secret.
NonceFn	A nonce generation function. Ordinary users of the library never need to see this type; only if you need to control nonce generation do you need to use it. I have deliberately made this hard to do: you have to write your own wrapper around the FFI functions to use it. And it's an unsafe type. Nonces are generated deterministically by RFC6979 by default; there should be no need to ever change this.
SchnorrNonceFn	Same as secp256k1_nonce function with the exception of accepting an additional pubkey argument and not requiring an attempt argument. The pubkey argument can protect signature schemes with key-prefixed challenge hash inputs against reusing the nonce when signing with the wrong precomputed pubkey.
