Trait FromDigest 

pub trait FromDigest<C: PrimeCurve> {
    // Required method
    fn from_digest<D>(digest: D) -> Self
       where D: Digest<OutputSize = FieldSize<C>>;
}

Available on crate features hazmat and digest only.

Instantiate this type from the output of a digest.

This trait is intended for use in ECDSA and should perform a conversion which is compatible with the rules for calculating h from H(M) set out in RFC6979 section 2.4. This conversion cannot fail.

This trait may also be useful for other hash-to-scalar or hash-to-curve use cases.

Required Methods

fn from_digest<D>(digest: D) -> Self

where D: Digest<OutputSize = FieldSize<C>>,

Instantiate this type from a Digest instance

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
