BigNumContext

rama::crypto::dep::boring::bn

Struct BigNumContext 

pub struct BigNumContext(/* private fields */);
Available on crate features boring and crypto and std only.
Expand description

Temporary storage for BigNums on the secure heap

BigNum values are stored dynamically and therefore can be expensive to allocate. BigNumContext and the OpenSSL BN_CTX structure are used internally when passing BigNum values between subroutines.

Implementations§

§

impl BigNumContext

pub fn new() -> Result<BigNumContext, ErrorStack>

Returns a new BigNumContext.

This corresponds to BN_CTX_new.
