Module secp256k1::ffi

FFI bindings

Direct bindings to the underlying C library functions. These should not be needed for most users.

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.
PublicKey	Library-internal representation of a Secp256k1 public key
RecoverableSignature	Library-internal representation of a Secp256k1 signature + recovery ID
SharedSecret	Library-internal representation of an ECDH shared secret
Signature	Library-internal representation of a Secp256k1 signature

Constants

SECP256K1_SER_COMPRESSED	Flag for keys to indicate compressed serialization format
SECP256K1_SER_UNCOMPRESSED	Flag for keys to indicate uncompressed serialization format
SECP256K1_START_NONE	Flag for context to enable no precomputation
SECP256K1_START_SIGN	Flag for context to enable signing precomputation
SECP256K1_START_VERIFY	Flag for context to enable verification precomputation

Type Definitions

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.
