Function ecdsa_verify_prehashed 

Source 
pub fn ecdsa_verify_prehashed(
    sig: <PassPointerAndRead<&Signature, 65> as RIType>::Inner,
    msg: <PassPointerAndRead<&[u8; 32], 32> as RIType>::Inner,
    pub_key: <PassPointerAndRead<&Public, 33> as RIType>::Inner,
) -> <bool as RIType>::Inner
Expand description

Verify ecdsa signature with pre-hashed msg.

Returns true when the verification was successful.

Note: This function does not enforce low-S signature normalization. Callers that require canonical (BIP-62 / EIP-2) signatures should check [sp_core::ecdsa::is_signature_normalized] before calling this function.
