Trait DigestPrimitive

Source
pub trait DigestPrimitive: PrimeCurve {
    type Digest: BlockSizeUser + Digest<OutputSize = Self::FieldBytesSize> + FixedOutput + FixedOutputReset;
}
Expand description

Bind a preferred Digest algorithm to an elliptic curve type.

Generally there is a preferred variety of the SHA-2 family used with ECDSA for a particular elliptic curve.

This trait can be used to specify it, and with it receive a blanket impl of PrehashSignature, used by signature_derive) for the Signature type for a particular elliptic curve.

Required Associated Types§

Source

type Digest: BlockSizeUser + Digest<OutputSize = Self::FieldBytesSize> + FixedOutput + FixedOutputReset

Preferred digest to use when computing ECDSA signatures for this elliptic curve. This is typically a member of the SHA-2 family.

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.
